Radiology Subspecialties
Radiology subspecialties compared: work, procedures and on call
On this page
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.
Comparison
| Subspecialty | Focus | Procedures | On call load |
|---|---|---|---|
| Interventional radiology | Image guided treatment, vascular and non vascular | Daily | High |
| Neuroradiology | Brain, spine, head and neck | Some; neurointervention is a separate path | Moderate to high (stroke) |
| Musculoskeletal | Bone, joint, soft tissue, sports | Injections, biopsies | Low |
| Breast | Screening and symptomatic mammography, ultrasound, MRI | Biopsies, localisation | Minimal |
| Cardiothoracic | Cardiac CT and MRI, chest CT, lung cancer | Few | Low to moderate |
| Abdominal and body | GI, hepatobiliary, GU, gynaecological, oncology | Some | Moderate |
| Paediatric | All modalities in children, dose optimisation, safeguarding | Some | Varies |
| Nuclear medicine and PET | PET-CT, SPECT, radionuclide therapy, theranostics | Some | Low |
| Emergency | Acute and trauma imaging | Few | High, often shift based |
| Head and neck | ENT, skull base, thyroid, salivary | Ultrasound guided biopsy | Low |
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.
