Interventional Radiology refers to a range of diagnostic and treatment procedures that are performed under the guidance of x-ray, CT scan, ultrasound or other imaging methods. The procedures most commonly performed are:

• biopsies (take out tissue samples from diseased organs)
• percutaneous drainage procedures (drain out fluid/pus collection)
• embolization (blocking bleeding or abnormal blood vessels)
• angioplasty (open blocked blood vessels)
