Interventional radiology is a medical specialty that uses imaging techniques, such as X-rays, CT scans, and ultrasound, to guide minimally invasive procedures. These procedures often involve inserting small instruments through tiny incisions to diagnose or treat various conditions, such as tumors, blood clots, or vascular issues. This field allows doctors to perform complex treatments without the need for large surgical openings, leading to shorter recovery times and less pain for patients. Common interventional radiology procedures include angioplasty, stent placement, and biopsies, making it a vital part of modern medicine.
