Below is the current list of 300 free anatomy thesis topics on major arteries, covering the thoracic and abdominal aorta, carotid and cerebral circulation, the Circle of Willis, visceral and renal branches, and the arteries of both limbs, for MD and DNB candidates in Anatomy. These also serve as arterial anatomy research topics for board residents and postgraduate students outside India. Each title uses a cross-sectional, observational, comparative or analytical design that can be completed from archived computed tomography angiography, Doppler ultrasonographic examination of consenting volunteers, or cadaveric dissection, without any additional radiation or contrast exposure. Every topic generates a complete anatomy protocol and anatomy synopsis in editable format.

The topics above work as research questions anywhere — what changes is the document your institution expects. Two different routes, depending on which applies.
Board residents — SCFHS, Arab Board, OMSB, KIMS, QCHP, NHRA, DHA and DOH
Residency programmes across the Gulf carry a mandatory research requirement, and the equivalent of an Indian synopsis is the research proposal submitted to the IRB before a research project begins. The format differs from the Indian one: it additionally requires a Gantt chart, a budget and resources section, and a Declaration of Helsinki statement.

University graduate programmes generally require a full research proposal of roughly 6,000 to 10,000 words, with an extended literature review, a theoretical framework and a detailed methodology chapter — considerably longer and deeper than a residency proposal. These are written individually, by a medical doctor, with no artificial intelligence generation and no plagiarism, and revised until the supervisor accepts them.

Based on recent dissertations and examiner preferences in anatomy departments across India, these are the emerging high-interest areas:
An arterial morphometric protocol is judged on internal consistency: the research question, objectives, methodology and statistical plan must all describe the same study. The primary objective should be a single measurable endpoint — one set of dimensions, one prevalence, one comparison — with everything else demoted to secondary objectives.
An artery changes calibre through the cardiac cycle, so state the phase. Unlike a vein, an artery does not collapse under gentle pressure, but it does pulsate, and the systolic and diastolic diameters of a large elastic vessel differ appreciably. On ultrasound, state whether the measurement is taken at end-diastole, which is the usual convention, or at peak systole, and how the frame was identified — by electrocardiographic gating or by visual selection from a cine loop. On computed tomography, state whether the acquisition was electrocardiographically gated, because an ungated study of the ascending aorta and root averages across the cycle and adds motion artefact, so the reported diameter carries an uncertainty the protocol should acknowledge rather than conceal.
Measure perpendicular to the vessel, not on the axial slice. This is the largest and most avoidable source of error in arterial morphometry. A vessel running obliquely through an axial plane is cut as an ellipse, and the maximum diameter of that ellipse overstates the true calibre — markedly so in a tortuous aorta, a kinked internal carotid artery or an angled renal artery. State that measurements were made on double-oblique reformatted images perpendicular to the vessel centreline, or on centreline-derived cross-sections generated by the workstation, and name the software. State also the edge convention: inner-edge to inner-edge or outer-wall to outer-wall, since the two differ by twice the wall thickness and published reference values specify which they used.
Index aortic and large vessel dimensions to body size. Absolute aortic diameter is close to uninterpretable across a population of varied stature and build, which is why the aortic literature reports values indexed to body surface area. Give the formula used to calculate body surface area, since more than one is in general use, and report both the absolute and the indexed value. The same reasoning applies to the iliac and femoral vessels where the study population spans a wide range of body size.
Write down the threshold before counting a variant. This decides several sections of this list. A segment of the Circle of Willis called hypoplastic in one study is called present in another purely because the diameter threshold differs, and published prevalence of a complete circle consequently ranges from roughly a fifth of subjects to roughly four fifths. State the threshold in millimetres, cite its source, and apply it uniformly. Do the same for a dominant vertebral artery, a foetal-type posterior cerebral artery, a complete as against incomplete palmar arch, an accessory as against a polar renal artery, and a high brachial or popliteal division. Where a published classification exists — for aortic arch branching type, coeliac trunk configuration or internal iliac branching pattern — name it and reproduce its categories in an annexure.
Recognise that detection depends on technique. Reported prevalence of small accessory vessels rises as slice thickness falls, so an accessory renal artery series acquired at five millimetres and one acquired at one millimetre are not comparable, and neither is directly comparable with a cadaveric series where every vessel can be traced by hand. State the acquisition parameters and note this explicitly in the discussion rather than attributing the difference from published figures to population variation.
Match the modality to the question in cadaveric work. An embalmed artery retains its shape better than a vein because of its muscular and elastic wall, but it is neither perfused nor pressurised, and fixation alters dimensions, so a diameter measured on a dissected vessel is not a living calibre and should not be presented as one. Cadaveric dissection excels at what angiography does poorly: branching order, the exact level of an origin, small named branches, relationships to nerves and muscles, and the completeness of anastomotic arches. Where a cadaveric topic here is framed as morphometric, restrict measurements to length, level and distance from a landmark, and say why calibre is not reported.
Say who measured, and show it was reproducible. Name the observer, repeat measurements on a defined subset at a separate sitting, and have a second observer independently measure the same subset blinded to the first readings. Report the intraclass correlation coefficient for continuous values and Cohen's kappa for branching and variant classification, which is judgement rather than measurement and needs its own agreement figure.
An anatomy synopsis is the condensed document of two to four pages — title, introduction, aim and objectives, brief methodology, sample size and references — submitted for registration of the dissertation topic. The anatomy protocol is the expanded version of twelve to twenty pages carrying the full review of literature, detailed methodology including acquisition parameters, measurement conventions and variant definitions, the statistical plan, study timeline and annexures.
Three annexures matter here. The measurement convention annexure should state, for every vessel measured, the plane of measurement, the edge convention, the cardiac phase and the anatomical level, in terms another observer could follow without asking. The variant definition annexure should give the numerical threshold for every variant the study will count and reproduce any classification scheme used, since the results tables are otherwise uninterpretable and the figures cannot be compared with published series. And where living volunteers undergo Doppler examination, the full consent set is required in the local language.
The consent requirements differ sharply across this list, and the annexure set follows from which of three study types the topic is. A retrospective angiographic study needs an explicit waiver of consent. A Doppler study on volunteers needs full written informed consent. A cadaveric study needs neither but must address the governing anatomy legislation. Decide before drafting.
In practice the synopsis is extracted from the protocol rather than written separately, which is faster and produces a more coherent document. Check the university's prescribed proforma before submission, since rejections on formatting grounds are common and entirely avoidable.
Match the formula to the design. Descriptive morphometric studies size on the expected mean and standard deviation of the principal measurement, taken from a cited study in a comparable population, with a stated absolute precision. Comparative studies between two groups need a two-mean calculation with both expected values referenced. Variant prevalence studies use a proportion-based calculation, and because many arterial variants are uncommon, use relative rather than absolute precision or the sample will come out implausibly small. A study of aberrant obturator artery or superficial ulnar artery needs numbers that only an archive or a large cadaveric series can supply.
Right against left is paired here. Both sides come from the same individual on the same examination or in the same cadaver, so the observations are dependent and the paired t-test or Wilcoxon signed-rank test applies, as does McNemar's test where the comparison is of a binary variant between sides. The same holds for dominant against non-dominant limb comparisons. State this explicitly, because a bilateral arterial study analysed with an unpaired test is the commonest analytical criticism these dissertations attract.
Report indexed values where body size varies. For aortic, iliac and femoral dimensions, present both the raw measurement and the value indexed to body surface area, and use the indexed value for any comparison between sexes, since much of the apparent difference between male and female aortic diameter disappears once body size is accounted for. A study reporting only absolute values and concluding that men have larger aortas has described body size rather than arterial anatomy.
Agreement, not correlation, for method comparisons. Where two modalities measure the same vessel — Doppler against computed tomography angiography, surface landmark against imaging localisation — the analysis is Bland-Altman with limits of agreement. Two methods can correlate almost perfectly while one reads systematically larger, which is precisely what happens when an axial measurement is compared with an orthogonal one. For branching and variant classification, report Cohen's kappa from an independent second assessment of a defined subset.
Be honest about what a hospital archive represents. Every patient whose angiogram appears in the archive had an indication for it, and several of the conditions prompting a computed tomography angiogram alter arterial calibre directly — hypertension, atherosclerosis, aneurysmal disease, connective tissue disorder. State exclusion criteria in those terms, exclude studies showing significant atheromatous or aneurysmal change in the vessel measured, and avoid presenting the resulting figures as normal reference values without qualification. Where the title says healthy adults, the sampling frame must support the claim.
Name the tests. Continuous measurements are summarised as mean with standard deviation and range, with normality formally tested. Independent groups use the t-test or Mann-Whitney U test, within-person comparisons the paired equivalents, and three or more groups analysis of variance or the Kruskal-Wallis test with a stated post-hoc correction. Proportions and variant frequencies use the chi-squared test with Fisher's exact test for sparse cells, which are frequent when uncommon configurations are tabulated by side or sex. Correlation uses Pearson where both variables are normally distributed and Spearman otherwise, reported with confidence intervals rather than the p value alone.
Decide first which of three kinds of study the topic is, because feasibility, ethics and achievable numbers all follow from it. An archived angiographic study depends on radiology cooperation and on whether the source images, rather than the reports, can be retrieved and reformatted. A Doppler study on volunteers depends on machine access, on someone competent to scan, and on how long each examination takes. A cadaveric study depends on the department's dissection programme and on whether the region will still be intact when you need it.
Then count realistically against the variant you intend to study. Common findings — carotid bifurcation level, aortic arch branching type, brachial bifurcation level — are reachable in a hundred or two hundred cases. Uncommon ones such as aberrant obturator artery, superficial ulnar artery or absent dorsalis pedis need several hundred, which in practice means the archive or a pooled cadaveric series over several years.
One practical check before committing to any angiographic topic: confirm that the workstation allows double-oblique reformatting and centreline measurement, and that you will have access to it for the hours the study needs. Measuring three hundred vessels perpendicular to their axis is slow, and doing it on a machine that is busy with clinical reporting is the constraint that most often derails these projects.
Descriptive morphometric studies dominate: calibre, length and level of a named artery measured across a series, reported with means, standard deviations and ranges, and compared with published values. Prevalence studies of anatomical variants, comparative studies between sides or sexes, classification studies assigning specimens to named branching types, and correlation studies relating arterial dimensions to anthropometric parameters are all well established.
Cadaveric variation studies remain the classical design in this speciality and continue to publish well, particularly for branching patterns and small named branches that angiography cannot resolve. Studies framed around clinical procedure — radial artery dimensions for transradial access, iliac dimensions for endovascular device sizing, hepatic arterial variation before transplantation — publish especially well because the anatomy has direct application. Comparisons of angiographic against cadaveric findings for the same structure are an accepted design in their own right and address a genuine question about how the two methods differ.
Bring three to five shortlisted titles rather than one, since guides frequently rule out a topic on grounds that are not visible to a new resident — a departmental study already running, a senior resident holding an overlapping subject, a scanner replacement that splits the archive into two acquisition protocols.
Settle five things in that meeting: which of the three study types the topic is and therefore what the ethics submission looks like, whether radiology will release source images and workstation time rather than reports, what threshold will define each variant to be counted, who will act as the second observer for the agreement analysis, and which journal the eventual paper is aimed at. Where cadaveric material is involved, confirm the region will be available before routine teaching dissection reaches it, since an arterial pattern divided during a first-year dissection cannot be recovered.
Yes, and for the aorta, visceral and pelvic vessels it is usually the only realistic route. State the archive period, how studies were identified, and the exclusion criteria, which here must be specific: exclude studies showing significant atheromatous disease, aneurysm, dissection, stenosis, previous vascular surgery or stenting in the vessel measured, and any acquisition inadequate for reformatting.
Four cautions. Contrast phase and timing. An arterial study acquired too late shows venous contamination and poor arterial opacification; restrict to a stated arterial phase with the bolus tracking method described. Gating. Ungated acquisitions blur the ascending aorta and root; if the archive is ungated, say so and confine conclusions accordingly. Slice thickness. Detection of small accessory vessels depends directly on it, so record it per case and check whether prevalence differs across acquisition protocols before pooling. Indication bias. Everyone in the archive was scanned for a reason, frequently a vascular one, so the series is not a healthy population and the discussion must say so rather than offering the figures as normal reference values.
The synopsis is the condensed two to four page document submitted for topic registration. The protocol is the full document of twelve to twenty pages containing the detailed review of literature, methodology with acquisition parameters, measurement conventions and variant definitions, the statistical plan, timeline and annexures. The synopsis is normally extracted from the completed protocol.
Institutional ethics committee approval before data collection, with requirements that differ substantially by study type.
Volunteer Doppler examination. These participants are research subjects. Written informed consent is required, with an information sheet in the local language explaining that the examination is non-invasive and painless, roughly how long it takes, that no contrast or radiation is involved, and that participation is voluntary and does not affect any clinical care. State what happens if an unexpected finding appears during the scan — a plaque, a stenosis, an aneurysmal segment — because in an adult population this will occasionally occur, and the protocol must say the participant is informed and referred rather than the finding being recorded silently as data.
Archived angiography. Apply explicitly for a waiver of consent rather than assuming it. State that identifiers are removed before measurement, that a study code replaces the hospital number, and that the linking key is held separately. Confirm that no participant underwent any additional examination and that the study adds no radiation or contrast exposure, since a living person may not be scanned or injected for a dissertation.
Cadaveric dissection. State that the material forms part of the department's body donation and teaching programme, held and used in accordance with the governing anatomy legislation, and that no body was acquired for the study. Where vessels are injected with latex or dye for demonstration, describe the technique and confirm it does not compromise the teaching value of the specimen.
Pelvic and genital arterial topics. The uterine, pudendal and vesical arterial studies involve intimate anatomy, and although the material is cadaveric, figures and photographs need particular care over anonymity and dignity of presentation. Address this explicitly.
Clearance commonly takes six to ten weeks and retrospective approval is not granted.
Almost entirely because of definition and method rather than because populations differ, and understanding why is what makes a Circle of Willis dissertation defensible. Published figures for a complete circle range from around a fifth of subjects to around four fifths, which is far too wide to be biological. Three things drive it. The hypoplasia threshold. There is no universally agreed diameter below which a communicating artery is called hypoplastic rather than simply small; different series use different cut-offs, and moving the threshold by a few tenths of a millimetre moves a large number of specimens from one category to the other. State the threshold, cite where it comes from, and apply it to every specimen. The resolution limit of the method. Magnetic resonance angiography cannot reliably resolve vessels below roughly a millimetre in diameter, so a communicating artery that is present but very small may be reported as absent. A cadaveric dissection, where the vessel can be traced by hand under magnification, will find it. This means angiographic and cadaveric series are systematically not comparable, and a study comparing its findings with published values must compare like with like or explain why it cannot. What counts as complete. Some authors require all component vessels to be present and of adequate calibre; others require only anatomical continuity regardless of size. Reproduce your definition in full in an annexure. Handled properly, this is a strength rather than a weakness: a study that states its threshold, acknowledges its resolution limit and compares itself only against series using comparable criteria produces a figure that means something, and the discussion of why other figures differ is often the most interesting section of the thesis.
Substantially. A PhD proposal typically runs 6,000 to 10,000 words and carries an extended critical literature review, a theoretical framework, a detailed methodology chapter and a discussion of expected contribution to the field. An MD synopsis is a two to four page registration document. The research question can be the same; the depth expected is not.
Most universities require registration within six to nine months of joining. Shortlist in the first two months, finalise with the guide by the third, and file for ethics clearance immediately afterwards. Angiographic topics need workstation time that must be negotiated in advance, Doppler topics need a scanning run-in before the measurements become reliable, and cadaveric topics follow the dissection calendar rather than the resident's timetable. Close the collection window at least six months before submission.
