Acute Abdomen, Mesentery, Peritoneum and Trauma
Integrate bowel, mesenteric, vascular, peritoneal and solid-organ findings in acute and traumatic presentations.
How to prepare for the current Final FRCR Part A
Build general-radiology breadth, then practise integrating clinical context, anatomy, multimodality findings, technique and management to select the single best answer.
Core concepts
Concept 1
Use free gas, fluid, enhancement, mesenteric change, vascular patency and injury mechanism to detect time-critical disease.
Exam cue: Localise the abnormality and identify the organ, compartment, tissue or vessel before naming a diagnosis.
Concept 2
Optimise portal venous, arterial or multiphase CT according to suspected bleeding, ischaemia, trauma and intervention.
Exam cue: Use age, clinical setting, tempo and the complete multimodality pattern to rank the most likely explanation.
Concept 3
Communicate active haemorrhage, ischaemia, perforation, unstable injury and drainable infection directly and promptly.
Exam cue: Select the examination or intervention that changes management while accounting for contrast, radiation, access and urgency.
Concept 4
Apply normal and variant anatomy, modality technique, image quality and relevant imaging science to acute abdomen, mesentery, peritoneum and trauma.
Risk pitfalls and guardrails
Focusing on one organ while missing the vascular, bowel, mesenteric and extra-abdominal injuries that determine urgency.
Guardrail: Do not anchor on one remembered sign; verify age, localisation, distribution, technique, alternatives and management consequence.
Do not choose a merely plausible SBA option before comparing every option with the full clinical and imaging context.
Guardrail: Re-read the command word and compare every option; the task is to select the best available answer, not the first plausible one.
Memory anchors
Active CT bleeding
Contrast extravasation changes shape or attenuation across phases and must be distinguished from calcification or retained contrast.
Closed-loop obstruction
Two transition points isolate a segment; assess configuration, mesenteric vessels and ischaemia urgently.
Abdominal trauma report
State injury grade-relevant features, active bleeding, vascular injury, hollow-viscus signs and associated injury.
Peritoneal disease clue
Distribution along surfaces, omentum and dependent recesses helps distinguish implants, inflammation and fluid processes.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.

Check-up Questions
A patient has sudden severe abdominal pain. CTA shows an SMA embolus, poor small-bowel enhancement and portal venous gas. What is the diagnosis?
A shocked intensive-care patient develops abdominal distension. CTA shows diffusely narrowed mesenteric arterial branches, poor bowel enhancement and no focal occlusion. What is the diagnosis?
Answer all questions to submit.
