CR1 Anatomy exam – What you need to know
Article by: Dr Alex Haworth
What are some of the most common mistakes candidates make in the CR1 Anatomy exam? Dr Alex Haworth, Chair of the CR1 Anatomy Exam Board, shares examiner insights on preparation, content and technique to help candidates succeed.
The FRCR Anatomy exam is one of your earliest milestones and plays a significant role in building safe, effective radiology practice. It is designed to assess your ability to recognise anatomy as it appears on imaging, which is often quite different from what you may remember from medical school or dissection-based learning. Developing this imaging-based understanding of normal anatomy early will make learning pathology significantly easier later on.
Content
The exam consists of 100 image-based questions completed over 90 minutes on a computer-based platform (RISR), where you type in your answers. The software is not a PACS, though questions are chosen which do not require manipulation to be answered. I would strongly recommend familiarising yourself with the exam delivery software in the demonstration site, accessible through the RCR website.
In terms of content, the exam is evenly distributed across the major anatomical regions: chest and cardiovascular, head/neck and spine, musculoskeletal, and abdomen and pelvis. Questions are drawn from a range of imaging modalities, including plain radiography, CT, MRI, ultrasound and contrast studies. Importantly, the exam also includes clinically relevant normal variants and a small proportion of paediatric anatomy, both of which are common sources of diagnostic error in early training. The blueprint for the exam can be found on the RCR CR1A guidance page.
Preparation
Success in the anatomy exam requires a shift in how you approach learning. Radiological anatomy varies depending on the imaging modality, acquisition technique, and even patient factors, and this can make early interpretation challenging. Ultrasound as a dynamic examination can pose particular challenges.
As with most examination techniques, pause if you find yourself uncertain. Take a breath and look for landmarks that you know. The answer can usually be worked out from the other anatomy shown on the image.
While textbooks are helpful, the most effective learning comes from day-to-day clinical exposure, reviewing cases, attending ultrasound sessions and observing multidisciplinary discussions. This helps anchor anatomical knowledge with clinical relevance, which not only improves understanding but also retention.
Candidates who struggle with the exam often underestimate the depth of anatomical knowledge needed or rely too heavily on passive study methods such as reading alone and repeated use of online anatomy questions. Anatomy should be approached with the same seriousness as other components of the FRCR, including physics. Integrating anatomy learning into everyday clinical work is one of the most effective ways to improve performance and build your confidence.
The board is not looking to catch candidates out or trip them up. The exam can be difficult but with preparation and clinical exposure it should not pose an insurmountable bar.
Read the question stem
From an examiner’s perspective, many candidates lose marks through avoidable errors rather than through a lack of knowledge. Carefully reading the question (and the name of the examination shown) is critical, as different question stems require subtly different responses. While ‘name the arrowed structure’ is the most common format, you may also be asked to identify a variant or name one structure passing through a given space, so be careful to read the question before answering.
Overcomplicating
Precision is essential in all answers. You should clearly distinguish between closely related anatomical structures, such as muscles and their tendons, and be specific when describing vessels with segmental anatomy. If a paired structure is shown, it is mandatory to identify the correct side, as this is clinically important. Don’t fall into the trap of writing ‘left or right’ before every answer though, just in case. There is not a ‘left splenic artery’.
Over-answering does not gain extra marks and may reflect poor exam technique. If we ask for one structure, then only name one. Candidates sometimes try to show the depth of their knowledge by naming multiple structures passing through a space. While this is commendable, a single incorrect answer will negate all the hard work and lead to zero marks on that question.
Abbreviations
Abbreviations should be avoided. We expect full anatomical terminology to show clear understanding. This is a postgraduate exam, after all. When marking abbreviations, we cannot know whether you know that ‘SMA’ stands for ‘Superior Mesenteric Artery’ or if you think it means something else.
Keep to time
90 minutes seems like a long time, but when you are focused and in an exam environment, you can quickly lose track. If you are pondering a question, consider flagging it in the software and moving on (a good reason to practice on the demonstration site). You can come back to it later. Once you have attempted all the questions, revisit those that you have flagged. It may be that in answering the other questions you have remembered or worked out the answer to an earlier question.
Final words
Success in the CR1 Anatomy exam comes down to careful reading of questions, precise and specific answers, and consistent exposure to anatomy in your clinical practice. By focusing on applied, modality-specific anatomy and making the most of daily learning opportunities, you will build a sturdy foundation for both the exam and your future radiology career. It is much easier to build pathological knowledge on top of a sound anatomical foundation.
Good luck.
