Interventional radiologists are board certified and have special expertise in X-ray and imaging techniques, including CT scanners, MRI scanners and ultrasound scanners. Interventional radiology offers an alternative to the surgical treatments of many conditions and can eliminate the need for hospitalization, in some cases.

An X-ray of the arteries and veins to detect blockage or narrowing of the vessels. In many cases, the interventional radiologist can treat the blockages, such as those occurring in the arteries in the legs or kidneys, by inserting a small stent which inflates and opens the vessel. This procedure is called a balloon angioplasty.
The use of a small balloon on the tip of a catheter inserted into a blood vessel to open upan area of blockage inside the vessel.
Blood clot filters
A small filter is inserted into a blood clot to catch and break up blood clots.
Catheter insertionsA catheter is inserted into large veins for giving chemotherapy drugs, nutritional support and hemodialysis. A catheter may also be inserted prior to bone-marrow transplantation.
The insertion of a substance through a catheter into a blood vessel to stop hemorrhaging, or excessive bleeding.
Foreign body extraction
The use of a catheter inserted into a blood vessel to retrieve a foreign body in the vessel.
A gastrostomy tube (feeding tube) is inserted into the stomach if the patient is unable to take food by mouth.
Injection of clot-losing agents
Clot-losing agents, such as TPA, are injected into the body to dissolve blood clots, thereby increasing blood flow to the heart or brain.
The use of ultrasound inside a blood vessel to better visualize the interior of the vessel in order to detect problems inside the blood vessel.
A small needle is inserted into the abnormal area in almost any part of the body, guided by imaging techniques, to obtain a tissue biopsy. This type of biopsy can provide a diagnosis without surgical intervention. An example of this procedure is called the needle breast biopsy.
A tiny, expandable coil, called a stent, is placed inside a blood vessel at the site of a blockage. The stent is expanded to open up the blockage.
