Core concepts
Concept 1
Chest, abdominal and skeletal radiography plus point-of-care, abdominal, vascular and soft-tissue ultrasound.
Exam cue: Do not delay immediate treatment of a clinically obvious emergency while waiting for confirmatory imaging.
Concept 2
Confirm modality, orientation and image quality before identifying the decisive sign and its clinical implication.
Risk pitfalls and guardrails
Describing an abnormality without answering the clinical question or checking image adequacy.
Guardrail: Do not rely on a memorised label without orientation, relations and the clinical or operative consequence.
Selecting a technically true option that does not best answer the exact surgical task or time point.
Guardrail: Do not choose an option merely because it is true; select the safest answer that fits the exact task, level and time point.
