An Interventional Radiologist is a medical doctor who specializes in using imaging techniques, such as X-rays, CT scans, and ultrasound, to guide minimally invasive procedures. They treat various conditions by inserting small instruments through tiny incisions, often using catheters, to deliver treatments directly to the affected area. This approach typically results in less pain and quicker recovery times compared to traditional surgery. These specialists play a crucial role in diagnosing and treating conditions like tumors, vascular diseases, and gallstones. By combining their expertise in radiology and surgical techniques, interventional radiologists provide effective solutions while minimizing risks for patients.
