What is Interventional Neuroradiology? 

Neurology is the branch of medicine that deals with disorders of the nervous system, including the brain, spinal cord, peripheral nerves, and muscles. 

This covers a range of conditions such as acute neurological emergencies (e.g. stroke, meningitis, encephalitis, or Guillain-Barré syndrome), disorders that can be managed almost entirely in the community (e.g. epilepsy and migraine) and chronic disabling conditions (e.g. multiple sclerosis and Parkinson's disease), where multidisciplinary care is essential.

About one in eight of all GP consultations are for neurological symptoms, and approximately 20% of acute medical admissions are for a neurological problem. Changes in the age structure of the UK population will lead to increasing numbers of people with degenerative conditions of the brain such as dementia and Parkinson's disease.

How to become an Interventional Neuroradiologist

​

To become an interventional neuroradiologist in the UK, doctors follow a highly specialised postgraduate training pathway that combines radiology with advanced neurovascular intervention skills. Interventional neuroradiology focuses on minimally invasive, image-guided procedures used to diagnose and treat conditions affecting the blood vessels of the brain and spinal cord, such as aneurysms, arteriovenous malformations, and acute stroke.

​

The pathway begins with completion of medical school, followed by the two-year UK Foundation Programme. After this, doctors apply for Clinical Radiology specialty training through national recruitment. Clinical Radiology training lasts five years (ST1–ST5) and includes broad exposure to diagnostic imaging across all body systems. During this time, trainees must successfully pass all parts of the Fellowship of the Royal College of Radiologists (FRCR) examinations, which assess core knowledge, imaging interpretation, and clinical decision-making.

​

In the later stages of radiology training, trainees interested in neuroradiology undertake subspecialty training. This includes advanced imaging of the brain, spine, and head and neck, as well as exposure to neurovascular conditions. Following completion of core radiology training, doctors pursue advanced fellowship training in interventional neuroradiology, typically lasting one to two years, at accredited, high-volume centres. This fellowship provides hands-on experience in complex procedures, including mechanical thrombectomy for stroke, endovascular aneurysm treatment, and embolisation techniques.

​

On successful completion of training, doctors are awarded a Certificate of Completion of Training in Clinical Radiology with a neuroradiology subspecialty and can be appointed as consultant interventional neuroradiologists within the NHS. The role is technically demanding, involves significant on-call commitments, and requires close collaboration with stroke physicians, neurosurgeons, and neurologists. However, it is a rapidly evolving field with a major impact on patient outcomes, particularly in emergency stroke care, making it a highly rewarding and future-focused career choice.​

Life of an Interventional Neuroradiologist

​​

Life as an interventional neuroradiologist is highly variable and more procedure-focused than diagnostic radiology. Job plans differ, with some days entirely spent in interventional sessions and others split between procedures, MDTs, and reporting. While diagnostic radiologists have similar mixed days, their workload focuses more on imaging interpretation, ultrasound, fluoroscopy, and acute CT than on hands-on intervention, though INRs often still participate in acute or duty sessions.

​

Working hours are usually around 9–5 on normal days, but on-call commitments can be demanding and are the main challenge of the speciality. On-call rotas vary widely between centres, ranging from week-long cover with overnight call-ins to structured evening thrombectomy services. IR days are generally longer than diagnostic radiology days, and the physical demands, such as prolonged lead use, can be significant. The speciality is rewarding for those who enjoy procedures, direct patient treatment, and variety.

Research Opportunities

​

Interventional neuroradiology offers extensive research opportunities, particularly in the development and evaluation of endovascular devices such as stents, coils, flow diverters, and thrombectomy systems. There is significant scope for innovation, with ongoing clinical trials, collaboration with industry and engineers, and the ability to incorporate techniques and technologies from more established interventional specialties such as cardiology. As the field continues to evolve rapidly, there is a vast amount to learn, adapt, and refine, making it an exciting area for clinicians interested in research, device innovation, and translating advances into improved patient care.​

Future of Interventional Neuroradiology

 

Interventional radiology has evolved dramatically over the past two decades, with many procedures that were once theoretical concepts now forming part of routine clinical practice. Advances such as tumor ablation, percutaneous fistula creation, musculoskeletal embolization, and novel imaging and device technologies highlight a strong innovation pipeline that continually expands the scope of the specialty. This evolution reflects how inventive ideas, when systematically explored, can rapidly translate into day-to-day patient care.

​

Looking ahead, interventional radiology is poised for further transformation through translational research and technological innovation. Emerging areas such as image-guided gene and cell therapy, nanoparticle-based treatments, advanced tissue diagnostics, artificial intelligence–assisted and telerobotic procedures, and intelligent biomaterials may define routine practice in the coming decades. The future scope of IR is vast, reinforcing its position as a forward-looking specialty driven by research, adaptability, and continual clinical innovation.
