What is Interventional Radiology? Interventional Radiology (IR) refers to a range of techniques which rely on the use radiological image guidance (X-ray fluoroscopy, ultrasound, computed tomography [CT] or magnetic resonance imaging [MRI]) to precisely target therapy. Most IR treatments are minimally invasive alternatives to open and laparoscopic (keyhole) surgery.
Interventional radiologists commonly perform three types of biliary drainage procedures. External biliary drainage is performed by positioning a drainage catheter in the bile duct above the obstruction. The physician punctures the skin and passes a needle into one of the bile ducts. The needle is exchanged over a guidewire for a catheter, and the catheter is positioned and sutured in place.
