What is Interventional Radiology?

Interventional Radiology is a subspecialty of radiology where physicians use medical imaging (like X-ray, CT, ultrasound, MRI) to guide minimally invasive procedures for diagnosis (e.g., biopsies) or treatment of a wide range of conditions in nearly every organ system. These procedures are often alternatives to open surgery. Dr. Atri specializes in these image-guided procedures.

How long will my imaging test take?

The duration depends on the type of scan. A simple X-ray might take only a few minutes. Ultrasounds can range from 15 to 45 minutes. CT scans are usually quick once you're positioned (actual scan time is often under a minute), but total appointment time can be longer. MRI scans are typically the longest, often 30 to 60 minutes or more per body part being imaged.
