Independent guide: The RCR does not publish a fixed number of questions for each curriculum area. Use this page to organise broad preparation, then check the current candidate guidance and clinical radiology curriculum.

How to think about this curriculum area

This curriculum area brings together thoracic imaging, cardiac imaging and peripheral or central vascular disease. The challenge is not simply remembering characteristic diagnoses: many single-best-answer questions ask you to interpret morphology, recognise a complication, choose the next imaging step or distinguish a true abnormality from contrast timing and physiological artefact.

A productive revision plan therefore alternates pattern recognition with applied decisions. Learn the core disease patterns, but repeatedly practise questions where the diagnosis is plausible and the decisive issue is severity, haemodynamic consequence, procedural planning or a subtle competing diagnosis.

What the area includes

  • Chest radiography and CT patterns in airways, infection, diffuse lung disease and thoracic oncology
  • Pulmonary vascular disease, acute pulmonary embolism and chronic thromboembolic disease
  • Aortic syndromes, aneurysms, congenital variants and endovascular planning
  • Cardiac anatomy, ventricular morphology, cardiomyopathy, valvular disease and postoperative imaging
  • Peripheral vascular ultrasound, CTA, MRA and interventional complications
  • Technique, contrast timing, artefact and clinically important incidental findings

Common single-best-answer tasks

Pattern plus distribution

Do not stop at a familiar word such as fibrosis, cysts or nodules. The zonal distribution, relationship to the secondary pulmonary lobule, associated lymphadenopathy, pleural findings and expiratory appearances usually carry the discrimination.

Severity and haemodynamic effect

Questions often move beyond naming the lesion to signs of right-heart pressure overload, ventricular dysfunction, vascular compromise, malperfusion or impending rupture. Review the imaging consequences, not just the primary diagnosis.

True lesion or artefact

Mixing of opacified and unopacified blood, pulsation, flow-related signal loss and postoperative material can mimic disease. Trace vessels in multiple planes and use delayed or alternative acquisitions appropriately.

Planning and complications

Know what the surgeon or interventionalist needs: landing zones, branch-vessel relationships, coronary course, valve-root measurements, chest-wall or mediastinal invasion and recognised device complications.

A practical revision framework

1

Build a thoracic pattern table

For each major CT pattern, record distribution, two supportive findings, two close differentials and the single feature most likely to separate them. Keep the table short enough to revisit repeatedly.

2

Revise cardiovascular anatomy through cases

Use reformatted CT and MRI examples to identify chambers, valves, coronary origins, aortic branches and venous pathways. Anatomy retained through clinical cases is more useful than isolated lists.

3

Pair acute and chronic vascular disease

Compare acute pulmonary embolism with chronic thromboembolic disease, acute aortic syndromes with chronic dissection, and embolic occlusion with inflammatory or compressive vascular disease.

4

Finish with mixed timed blocks

Later in preparation, mix thoracic, cardiac and vascular questions. The real paper will not signal which subdomain or modality comes next, and switching accurately is part of the task.

Common revision mistakes

  • Learning named signs without the distribution or clinical context that makes them useful
  • Treating pulmonary-artery enlargement as a direct pressure measurement
  • Ignoring expiratory CT when small-airways disease is the actual problem
  • Calling every postoperative filling defect thrombus without considering material, timing or artefact
  • Revising thoracic imaging heavily while neglecting cardiac and peripheral vascular anatomy

Readiness checklist

  • I can describe the major HRCT distributions before naming a diagnosis.
  • I can recognise CT signs of right-heart pressure overload and their limitations.
  • I can distinguish acute from chronic pulmonary vascular disease.
  • I can identify major coronary and aortic variants relevant to risk or intervention.
  • I can interpret common post-treatment and postoperative thoracic appearances.
  • I can recognise vascular artefacts and know which additional phase or modality helps.
  • I can state the imaging information required for common cardiothoracic procedures.
  • I have completed mixed timed questions rather than revising each subdomain in isolation.

Frequently asked questions

How should I divide cardiothoracic and vascular revision?

Use repeated mixed cycles rather than completing thoracic, cardiac and vascular imaging once each. This helps preserve breadth and practises the switching required in a mixed SBA paper.

Do I need to memorise every named HRCT sign?

No. Prioritise signs that materially narrow a differential and learn them with distribution, associated findings and the closest competing diagnosis.

Are mock questions enough for this module?

No. Use questions to test application, but combine them with clinical imaging, MDT exposure, current guidance and image-rich reference material.
