Oesophagus, Stomach and Small Bowel
Evaluate dysphagia, obstruction, inflammation, bleeding, malabsorption and upper gastrointestinal neoplasia.
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 site, mural versus luminal process, length, enhancement, surrounding change and complications to rank benign and malignant causes.
Exam cue: Localise the abnormality and identify the organ, compartment, tissue or vessel before naming a diagnosis.
Concept 2
Select fluoroscopy, CT, CT enterography, MR enterography, ultrasound, endoscopy or nuclear imaging for the clinical question.
Exam cue: Use age, clinical setting, tempo and the complete multimodality pattern to rank the most likely explanation.
Concept 3
Recognise perforation, closed-loop obstruction, ischaemia and active bleeding and direct urgent surgical, endoscopic or interventional pathways.
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 oesophagus, stomach and small bowel.
Risk pitfalls and guardrails
Describing bowel-wall thickening without assessing distension, enhancement, mesentery, transition points, vascular supply and extra-luminal complications.
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
Small-bowel obstruction essentials
Identify transition point, cause, degree, closed loop, ischaemia, perforation and downstream decompression.
Bowel ischaemia warning signs
Abnormal enhancement, mesenteric vessel occlusion, pneumatosis, portal venous gas and disproportionate fluid are concerning in context.
Enterography choice
CT is rapid and widely available; MRI avoids radiation and offers repeated assessment but is slower and motion-sensitive.
Dysphagia localisation
Separate oropharyngeal dysfunction from structural or motility disease of the oesophagus before choosing the examination.
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 progressive dysphagia. Barium swallow shows smooth tapered narrowing at the gastro-oesophageal junction with proximal dilatation and absent peristalsis. What is the most likely diagnosis?
A 72-year-old has weight loss and dysphagia. CT shows irregular eccentric distal oesophageal wall thickening with enlarged gastrohepatic nodes. What is the most likely diagnosis?
