Frequently Asked Questions

What is Interventional Radiology?

Interventional Radiology is a sub-speciality that involves treating patients through minimally invasive means under imaging guidance. Interventional Radiologists are minimally invasive specialists who use these techniques to treat a variety of conditions in the brain and body. The imaging techniques used can be angiography (x-rays), ultrasound or CT scan machine depending on condition treated.


Traditional methods of treatment for various conditions involved open surgery with incisions and long recovery times. Over the past couple of decades with advances in technology, there has been a tendency towards treating various conditions that were traditionally treated through open surgery, to now be treated through minimally invasive methods. These techniques extend across various specialities and various organ systems in the body. Over a period of time, these techniques have been refined further and in treatment of various conditions, these have replaced conventional open surgery as a first line option wherever feasible. It is one of the fastest growing fields in medicine with rapid and radical advances coming up on a regular basis.  


The obvious advantage is faster procedure time with quicker recovery. The risk of complications is much reduced. Ultimately, these techniques help patients immensely by improving quality of life. There has been a huge demand and patient acceptability has grown tremendously since these treatments were introduced in practice.  

How are the procedures done?

Majority of procedures do not require general anaesthesia, and are done under conscious sedation. The minimally invasive techniques usually involve small incisions less than 1 cm. The idea is to treat from “inside” rather than “outside”. As an example, for treating brain aneurysm which is a life threatening condition, the aneurysm is blocked from “inside “by reaching it through blood vessel of the groin all the way to the brain. It is quicker, faster and does not require opening of the skull to reach the area, with the same outcome as open surgery.  

What are the conditions treated?

There are multiple conditions that are treated used these techniques cutting across all specialties. Please explore the website to see the conditions for which these treatments are performed.
