What is interventional radiology?
Interventional radiology (IR) is a medical specialty in which doctors use medical imaging to guide small instruments through the body to diagnose or treat disease. Many procedures use a tiny skin opening and a catheter or needle, but the right approach depends on the condition, the evidence and the person.
A specialty shaped by imaging
Modern IR grew from early catheter-based vascular procedures in the 1960s, including work by radiologist Charles Dotter. Since then, imaging, devices and techniques have expanded the range of treatments that can be performed through small access points.
Who is an interventional radiologist?
An interventional radiologist is a physician with specialist radiology training and additional procedural expertise. Training pathways and qualifications differ between countries. They include interpreting scans, choosing suitable procedures, image-guided technical skills, patient communication, safety, and care before and after a procedure.
What tools do they use?
Catheter lab X-ray: live fluoroscopy and angiography help guide wires and catheters through blood vessels. Ultrasound: real-time sound-wave imaging can guide needles and assess vessels and organs. CT: detailed cross-sectional images help plan or guide selected procedures. MRI and other tools may also be used.
How does it fit alongside surgery?
For some conditions, an image-guided procedure may offer an alternative to an operation, or may complement surgery and medicines. Possible advantages can include a smaller skin opening and a different recovery experience. These benefits are not guaranteed: risks, effectiveness and recovery vary, and conventional surgery or non-procedural care may be more appropriate.
Why it matters in today’s care
IR combines imaging expertise with treatment. Interventional radiologists work with patients and other specialists to assess options, perform selected procedures and arrange follow-up. The goal is to choose a suitable treatment for the individual—not to use a procedure simply because it is minimally invasive.

Dr Sreenivasa Narayana Raju
I am a Vascular and Interventional Radiologist. Through this website, I share clear, evidence-informed education about image-guided treatment options for vein, uterine and thyroid conditions.
Every patient’s situation is different. I encourage patients and families to use this information to ask questions and have informed discussions with their treating doctor. The right next step depends on an individual assessment and should be decided with a qualified clinician.
