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 combined curriculum area is broad: renal and urinary imaging, adrenal disease, prostate and scrotal imaging, female pelvic imaging, obstetric complications and breast imaging all sit within one published domain. The breadth makes disciplined rotation essential.

Many questions are built around characterisation, anatomical localisation, protocol selection, treatment response or a safety-critical next step. Build reliable frameworks for common lesions and then practise switching between modalities and organ systems.

What the area includes

  • Renal masses, infection, obstruction, trauma, transplantation and urinary-tract intervention
  • Adrenal lesion characterisation, endocrine context and venous sampling anatomy
  • Prostate, bladder, urethral, penile, scrotal and paratesticular imaging
  • Uterine, ovarian, tubal and pelvic-floor imaging
  • Obstetric emergencies, placental disease and maternal imaging considerations
  • Breast screening, symptomatic assessment, MRI, implants, biopsy and treatment response

Common single-best-answer tasks

Characterise rather than label

Renal, adrenal, ovarian and breast lesions often require an imaging category, tissue clue or malignant feature. Use enhancement, fat, diffusion, signal, morphology and anatomical origin together.

Localise the organ of origin

Large retroperitoneal, pelvic and scrotal masses can obscure their source. Look for cortical defects, beaks, displaced vessels, an intact tunica or a separately identified ovary before deciding.

Select the correct pathway

Questions may test screening, first-line symptomatic imaging, problem-solving MRI, staging or intervention. The age, pregnancy status, symptoms and prior imaging determine the best next step.

Recognise treatment and procedural complications

Post-biopsy vascular lesions, transplant dysfunction, implant rupture, embolisation collateral supply and post-treatment fibrosis are recurring applied themes.

A practical revision framework

1

Rotate the subdomains deliberately

Do not let breast or pelvic imaging disappear behind renal and adrenal revision. Allocate recurring sessions to each component and use mixed blocks to confirm that knowledge remains accessible.

2

Build lesion-characterisation templates

For renal, adrenal, ovarian and breast lesions, use the same sequence: location, morphology, signal or attenuation, enhancement, diffusion, ancillary features and clinical context.

3

Revise anatomy through procedures

Adrenal veins, uterine and ovarian arterial supply, renal segmental vessels and pelvic compartments become more memorable when tied to intervention or spread of disease.

4

Separate safety rules from diagnostic rules

Pregnancy, contrast, breast intervention and acute haemorrhage questions may hinge on safety or urgency rather than the most elegant diagnostic modality.

Common revision mistakes

  • Treating all macroscopic-fat retroperitoneal lesions as arising from the nearest organ
  • Overcalling restricted diffusion without considering morphology and expected benign mimics
  • Confusing tubal opacification with demonstrated free intraperitoneal spill on HSG
  • Relying on a single breast-imaging descriptor rather than the complete assessment context
  • Neglecting pelvic-floor, urethral, paratesticular and procedural questions

Readiness checklist

  • I can use attenuation, chemical shift and enhancement to characterise adrenal lesions.
  • I can localise renal versus retroperitoneal and testicular versus paratesticular masses.
  • I can recognise important transplant and post-biopsy vascular complications.
  • I can interpret common uterine, ovarian and tubal imaging patterns.
  • I understand the imaging endpoint that demonstrates tubal patency.
  • I can choose appropriate breast imaging by age, symptom and clinical context.
  • I can recognise important implant and post-treatment breast appearances.
  • I have revised obstetric and maternal-imaging safety scenarios.

Frequently asked questions

How can I manage such a broad combined module?

Use a repeating rotation that gives every subdomain protected time, then combine them in mixed questions. Breadth is more reliable than completing one organ system perfectly and neglecting another.

Should I memorise every lesion classification?

Prioritise current classifications that directly affect reporting or management and understand the morphology behind them. Avoid superficial number recall without the imaging criteria.

Are screening questions different from diagnostic questions?

Yes. Screening, symptomatic assessment, staging and problem solving have different populations and pathways. Read the clinical setting before selecting a modality or interpretation.
