What is Interventional Radiology?

Interventional Radiology is the use of radiology to enable doctors to carry out diagnostic or treatment procedures under direct radiological vision. This X-ray procedure is used in minimally invasive surgery(MIS) – for example:

  • Angioplasty, the removal of stones from the kidney
  • Cholangiography, the observation of obstructions in the bile ducts

Interventional radiology includes the use of (but not limited to):

  • balloons
  • catheters
  • microcatheters
  • stents
  • therapeutic embolization (deliberately clogging up a blood vessel)

The specialty of interventional radiology overlaps with other surgical arenas, including interventional cardiology, vascular surgery, endoscopy, laparoscopy, and other minimally invasive techniques, such as biopsies.
