Airways, Infection and the Acute Chest
Recognise airway disease, infection and acute thoracic deterioration on radiographs and cross-sectional imaging.
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
Integrate distribution, tempo, airways, airspaces, pleura and clinical context to distinguish infection, oedema, collapse and obstructive disease.
Exam cue: Localise the abnormality and identify the organ, compartment, tissue or vessel before naming a diagnosis.
Concept 2
Choose radiography, CT, CT pulmonary angiography or ultrasound according to instability, suspected complication and the decision the result will change.
Exam cue: Use age, clinical setting, tempo and the complete multimodality pattern to rank the most likely explanation.
Concept 3
Identify tension, major airway obstruction, empyema, abscess and other findings requiring urgent drainage, intervention or escalation.
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 airways, infection and the acute chest.
Risk pitfalls and guardrails
Calling a non-specific opacity infection without checking volume loss, pleural disease, cardiac failure, aspiration pattern or an obstructing lesion.
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
Air-space opacity: first four checks
Distribution, volume change, air bronchograms and associated pleural or airway findings.
Lobar collapse clue
Displacement of fissures, hila or mediastinum supports volume loss rather than simple consolidation.
Empyema versus lung abscess
Empyema is pleural and lentiform with obtuse margins; an abscess is intrapulmonary and more often round with an irregular wall.
Acute chest escalation
Prioritise immediately reversible threats: tension pneumothorax, major airway obstruction, haemorrhage and vascular catastrophe.
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 68-year-old man develops fever and productive cough after a stroke. CT shows dependent consolidation in the posterior upper lobes and superior lower-lobe segments. What is the most likely cause?
A chest radiograph shows right upper-lobe opacity with elevation of the horizontal fissure and upward displacement of the right hilum. What is the single best interpretation?
