What the RANZCR Clinical Radiology Examinations assess
RANZCR Clinical Radiology Examinations assess real-world diagnostic radiology decision-making across multiple modalities and body systems. Candidates typically work through case-based image interpretation and structured oral or viva-style questioning. You are expected to describe salient findings, offer a prioritised differential, recommend further investigation where needed, and explain management or communication steps—including urgent escalation of critical results.
That means preparation needs to go beyond recognising diagnoses. You need to communicate a reliable sequence: establish what study you are looking at, describe the important findings, state the most likely diagnosis and alternatives, then explain what should happen next. In a viva, a correct diagnosis without a clear account of urgency or action may leave important parts of the case unanswered.
The catalogue description does not specify a fixed number of papers, stations or questions. Check the official RANZCR website for current candidate information, examination requirements and any changes to the format. Use that information to plan logistics; use your study time to practise the decisions and explanations described above.
A useful practice target is to answer cases in a consistent order while adapting the detail to the image and clinical question. The examiner strip below turns the stated areas of emphasis into a checklist for practice.
The MySummaries examiner strip for RANZCR practice looks like this:

Build a revision board from your own material
Start with the material you already rely on: course notes, teaching files, lecture slides and annotated cases. Sort it into boards by practical task or system, rather than creating one enormous set of notes. A board on acute neuroimaging, for example, can bring together image approach, key differentials, next investigations and escalation actions.
For each topic, retain only information that changes interpretation or action. A useful section might contain a short image-reading sequence, a compact comparison table, or a few findings linked to their significance. Add a source or reference in your own study material where you need to verify a local protocol. Do not memorise a management pathway from an old slide without checking whether it remains current.
A board should help you retrieve the decision, not reproduce a textbook chapter. The example below uses a suspected acute intracranial haemorrhage case to show how findings, differential and next steps can sit together.
A MySummaries board on acute intracranial haemorrhage ends up looking like this:
- Confirm patient, study, coverage and image quality
- Inspect brain parenchyma, extra-axial spaces, ventricles and basal cisterns
- Compare with prior imaging when available
For suspected aneurysmal subarachnoid haemorrhage, urgent vascular imaging such as CT angiography may identify an aneurysm; follow local pathways and discuss with the responsible team.
- Acute blood may be hyperattenuating in sulci, fissures or basal cisterns
- Describe distribution and any associated intraventricular blood
- Look for hydrocephalus, mass effect and other acute findings
- Treat a new acute haemorrhage as a critical finding
- Contact the responsible clinical team promptly and confirm receipt
- Document the finding, recipient and time of communication
| Pattern or context | Consider |
|---|---|
| Blood centred in basal cisterns | Aneurysmal subarachnoid haemorrhage |
| Blood limited to a cortical sulcus | Consider non-aneurysmal causes in the clinical context |
| Hyperdensity that may mimic blood | Check for contrast, calcification or artefact |

Practise a repeatable answer structure
For each case, speak in a sequence that makes your reasoning easy to follow. A practical structure is:
- Technique and adequacy: identify the modality and relevant phase or sequence, then state any limitation that affects interpretation.
- Key findings: describe location, distribution and important positive or negative findings. Lead with the finding that changes immediate care.
- Most likely diagnosis: state it plainly and connect it to the imaging features.
- Differential: give a short, prioritised list and say which feature would help distinguish the alternatives.
- Next steps: recommend further imaging or tests only where they answer a clinical question; justify the choice.
- Management and communication: address urgency, escalation and documentation when the result is time-critical.
This is a framework, not a script to recite in full for every image. If the study is limited, say what cannot be assessed and what would resolve that limitation. If an acute critical finding is present, do not leave its communication until the end of a long differential.
Turn this framework into a small “must not miss” checklist for each board. Keep it short enough to rehearse before a case, but specific enough to catch consequential omissions.
The MySummaries core checklist for this board could be:

Sit cases aloud, not only in your head
Image recognition and spoken case presentation are different skills. A candidate may identify the abnormality while silently reviewing an image, then lose structure under questioning. Practise aloud with a timer and a case prompt. Record the response, then check whether you localised the finding, explained your leading diagnosis, addressed a meaningful differential and named the next action.
Use a consistent opening, but avoid filling time with normal findings that do not answer the question. If asked for a differential, rank it and give the discriminating feature. If asked what happens next, connect the investigation to the uncertainty it resolves. In an urgent case, state who needs to know and how promptly.
The following practice case demonstrates how a viva answer can be assessed against the platform’s own criteria. Those criteria are for practice feedback, not a statement of RANZCR’s official marking scheme.
A MySummaries marked oral case on suspected subarachnoid haemorrhage looks like this:
Examiner
A 58-year-old presents with sudden severe headache. The non-contrast CT shows hyperattenuation in the basal cisterns with blood extending into the Sylvian fissures. Describe the findings, give your leading diagnosis and immediate next steps.
The response moved from technique to findings and diagnosis, but the action plan came late.
ImproveLead with the acute finding, then use short signposts for diagnosis and next steps.
Blood was localised to the basal cisterns and Sylvian fissures; ventricular extension was not specifically addressed.
ImproveComment on ventricles, hydrocephalus and mass effect as well as the visible distribution.
Aneurysmal subarachnoid haemorrhage was appropriately prioritised, with limited explanation of alternatives.
ImproveLink the distribution to the leading diagnosis and briefly state relevant mimics or alternatives.
CT angiography was proposed but its purpose was not made explicit.
ImproveSay that vascular imaging is to look for an aneurysm, guided by the clinical context and local pathway.
The answer recognised urgency but did not specify direct communication and confirmation of receipt.
ImproveName the responsible team, communicate promptly and document the contact.
The language was clear overall, with one vague phrase: ‘get the team involved.’
ImproveUse precise wording about the critical result and the immediate communication step.
A strong answerThis is a non-contrast CT head, and the study is adequate for assessing the visible acute findings. There is acute subarachnoid blood centred in the basal cisterns and extending into the Sylvian fissures; I would also assess for intraventricular blood, hydrocephalus and mass effect. The distribution is concerning for aneurysmal subarachnoid haemorrhage. I would recommend urgent vascular imaging, such as CT angiography, to look for an aneurysm, in keeping with the clinical context and local pathway. This is a critical result: I would contact the responsible clinical team promptly, confirm they have received the information and document the communication.

Convert errors into targeted revision
After each practice case, record the exact omission rather than writing “revise haemorrhage”. Useful error labels include “did not assess hydrocephalus”, “did not explain why CTA”, or “forgot to confirm critical-result receipt”. Each label should become a question you can answer from memory.
Review errors in two ways. First, return to the source material and correct any knowledge gap. Second, repeat the case in a short spoken answer, making the missing action explicit. Revisit the same error after a gap; a correction that works only immediately after feedback has not yet become reliable.
Keep some sessions for cross-modality decisions. For a finding that remains uncertain, ask what the next test would clarify, whether the modality is appropriate for the clinical question, and what limitation should be communicated. Avoid naming another scan reflexively: explain why it is useful and what decision it could change.
Use audio to rehearse concise explanations
Audio review is useful between image sessions, but it should reinforce—not replace—case interpretation. Build a short lecture from a board section, listen for a clear explanation of the decision points, and pause to state the answer before hearing the next point. For example, practise moving from the CT distribution of subarachnoid blood to a vascular investigation and an urgent communication plan.

Start by describing where the blood is, not by guessing its cause. On a non-contrast CT, identify whether the hyperattenuation lies in sulci, fissures, basal cisterns or ventricles. Then assess for hydrocephalus and mass effect, because those findings affect urgency and the immediate conversation with the clinical team.
When blood is centred in the basal cisterns and extends into the Sylvian fissures, aneurysmal subarachnoid haemorrhage is an important diagnosis to prioritise. Do not stop at the label. Explain that vascular imaging, such as CT angiography, may be needed to look for an aneurysm, taking the clinical context and local pathway into account.
Now close the loop. A new acute haemorrhage is a critical result: contact the responsible team promptly, confirm receipt and document what was communicated. If the study is limited or the diagnosis uncertain, state that limitation clearly and say what further assessment would resolve it.

A weekly preparation loop
Use a repeatable cycle rather than dividing all your time between reading and full mock cases:
- Review: select a small board section and retrieve its key findings, differential and next step without looking.
- Interpret: work through cases across body systems and modalities, speaking your structured response aloud.
- Mark: compare the answer with your notes and record omissions as precise, testable questions.
- Repair: revise the weakest point, then repeat the case or answer a related case to test transfer.
- Consolidate: return to due cards and listen to a short board-based explanation where it helps clarify a decision.
At the end of the week, identify which errors were knowledge gaps and which were delivery or safety omissions. Knowledge gaps need targeted reading and retrieval practice. Delivery problems need recorded answers and tighter signposting. Safety omissions need repeated rehearsal until escalation and communication appear naturally in relevant cases.
Check current official RANZCR candidate guidance for the examination’s administrative details, and keep a log of your own weak areas as the basis for the next week’s practice.
