Interventional radiologists are medical doctors who specialize 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 a wide range of issues, including tumors, vascular diseases, and gallstones. Their expertise allows them to perform procedures like angioplasty and biopsies, making them essential in modern medicine.
