Abdominopelvic Vascular Supply
Aorta and branches, IVC and tributaries, portal venous system, iliac vessels and collateral pathways.
How to prepare for the current First FRCR
Build precise radiological-anatomy recall across modalities, then connect each Physics statement to image formation, quality, dose, safety and current UK regulation.
Core concepts
Concept 1
Aorta and branches, IVC and tributaries, portal venous system, iliac vessels and collateral pathways.
Exam cue: Trace each vessel from origin to branch or drainage and use enhancement phase plus neighbouring organs to confirm identity.
Concept 2
Separate arterial, systemic venous and portal pathways and distinguish parallel vessels at the porta hepatis and pelvis.
Exam cue: Separate arterial, systemic venous and portal pathways and distinguish parallel vessels at the porta hepatis and pelvis.
Risk pitfalls and guardrails
Naming a vessel from its brightness or position on one image without tracing continuity.
Guardrail: Do not answer from pattern familiarity alone; verify orientation, mechanism, units, assumptions and current terminology.
Memory anchors
What are the major unpaired anterior aortic branches?
Coeliac axis, superior mesenteric artery and inferior mesenteric artery.
How is the portal vein formed?
Usually by the union of the superior mesenteric and splenic veins behind the pancreatic neck.
What is the porta hepatis relationship?
Portal vein lies posterior to the hepatic artery and bile duct within the portal triad.
How should iliac vessels be distinguished?
Trace common iliac bifurcation to external and internal branches and follow venous confluence to the IVC.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
Knowledge Check (after reading)
Short check-up to confirm understanding of this module.
