Paediatric Gastrointestinal and Genitourinary Imaging
Assess vomiting, abdominal pain, obstruction, infection and congenital urinary or gastrointestinal disease in children.
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
Let age, symptom colour and tempo, gas pattern, ultrasound anatomy and congenital associations drive the differential.
Exam cue: Localise the abnormality and identify the organ, compartment, tissue or vessel before naming a diagnosis.
Concept 2
Use ultrasound and radiography first for many presentations, reserving fluoroscopy, CT, MRI and nuclear imaging for defined questions.
Exam cue: Use age, clinical setting, tempo and the complete multimodality pattern to rank the most likely explanation.
Concept 3
Recognise intussusception, volvulus, appendicitis, obstructed infection and testicular torsion and support therapeutic imaging where appropriate.
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 paediatric gastrointestinal and genitourinary imaging.
Risk pitfalls and guardrails
Using adult CT-first pathways when ultrasound, fluoroscopy or clinical escalation is more appropriate.
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
Intussusception pathway
Ultrasound confirms the diagnosis and assesses complications; enema reduction can be diagnostic and therapeutic in suitable patients.
Pyloric stenosis
Dynamic ultrasound assesses pyloric muscle and gastric passage; measurement must be technically sound.
Paediatric UTI imaging
Choose ultrasound, contrast study or radionuclide assessment according to age, recurrence, atypical features and the question.
Acute scrotum
Torsion is time critical; Doppler findings must be integrated with symptoms and should not delay surgery when suspicion is high.
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 6-week-old infant has projectile non-bilious vomiting. Ultrasound shows pyloric muscle thickening and an elongated canal with failure of gastric contents to pass. What is the diagnosis?
A toddler has intermittent colicky pain and redcurrant-jelly stool. Ultrasound shows concentric bowel rings with mesenteric fat in the centre. What is the diagnosis?
