In short: UK clinical radiology divides into diagnostic subspecialties by organ system or modality, plus interventional radiology, which has its own training programme. The main differences between them are the amount of procedural work, direct patient contact and on call. Most people decide during ST2 to ST3 rotations.

Short descriptions

Interventional radiology

The procedural subspecialty: angioplasty, embolisation, ablation, drainage and biopsy. Six year run through training in the UK. Full guide

Neuroradiology

Brain, spine and head and neck imaging. Stroke imaging drives on call. Neurointervention (thrombectomy, aneurysm coiling) requires additional training.

Musculoskeletal

Trauma, arthritis, infection, tumour and sports imaging, with ultrasound and fluoroscopic guided injections and biopsies.

Breast

Screening programme and symptomatic clinics. Regular direct patient contact, predictable hours, high volume.

Cardiothoracic

Coronary CT, cardiac MRI, chest CT including lung cancer screening and interstitial lung disease.

Abdominal and body

The broadest diagnostic subspecialty, spanning GI, hepatobiliary, pancreatic, genitourinary and gynaecological imaging, and much of oncology.

Paediatric

Congenital and childhood disease across modalities, with emphasis on dose and on safeguarding imaging.

Nuclear medicine

PET-CT, SPECT and radionuclide therapy. Growing quickly with theranostics. Some routes require dual accreditation.

How to choose

  • Procedures or reporting: which do you want most of your week to be
  • On call: how much, and can it be done from home
  • Patient contact: how much do you want
  • Academic interest: where are the research opportunities
  • Job market: what is advertised in the region you want to live in

Do not decide early. Use ST1 to ST3 rotations, request extra sessions in the areas you like, attend the MDTs and do an audit in the area. Many people change their mind during training.

Common questions

What are the subspecialties of radiology?

Interventional, neuroradiology, musculoskeletal, breast, cardiothoracic, abdominal, paediatric, nuclear medicine, emergency and head and neck, among others. Many consultants combine two.

Which radiology subspecialty has the best work life balance?

Breast, musculoskeletal and nuclear medicine typically have the least on call. Interventional and emergency radiology have the most.

When do radiology registrars choose a subspecialty?

Usually during ST2 to ST3 rotations, with subspecialty focus in ST4 to ST5. Interventional radiology is chosen at entry.
