Interventional Radiology - Departments & Programs, UW Hospital and Clinics

Interventional Radiologists (IRs) are physicians who specialize in minimally invasive, targeted treatments performed using imaging guidance. IRs use their expertise in reading X-rays, ultrasound and other medical images to guide small instruments such as catheters (tubes that measure just a few millimeters in diameter) through the blood vessels or other pathways to treat disease percutaneously (through the skin).

These procedures are typically much less invasive and much less costly than traditional surgery. They are generally easier for the patient because they involve no large incisions, less risk, less pain and shorter recovery times.

Are the patients sedated during interventional radiology procedures?

Patients may be under general anesthesia, or simple conscious sedation, or maybe they don't need any type of sedation.

During an interventional radiology procedure, how do the doctors know where they are inside the patient's body?

The physicians are highly trained in this profession so they have a strong anatomy background. This knowledge is assisted with the X-ray equipment that projects the image on a TV screen, so they can watch "real time" what they are doing with medical devices called catheters and wires.

During an interventional radiology procedure, who is in a procedure room?

The number of people present can vary from procedure to procedure. Depending on the circumstances, this can include a physician, (maybe a fellow and/or a resident,) a nurse and a radiologic technologist.

Is interventional radiology similar to cardiac cath?

Interventional radiology and cardiac cath are two very similar disciplines. They use similar X-ray equipment, both have highly trained staff, and both can be used to diagnose and treat patients.

Should I be concerned about radiation?

You should be minimally concerned if you are around it a minimal amount. You should be more concerned if you are frequently exposed to radiation. Those who work in Interventional Radiology daily have lead aprons to help limit their exposure. Also, specific training helps keep the ALARA (As Low As Reasonably Achievable) at the forefront.

TIP: Distance is your friend. The more distance between you and the beam, the less exposure you will receive.

What does I.R. mean?

I.R. = Interventional Radiology. In this case, "interventional" means to intervene, or fix something.

What is DVI?

DVI is a term specifically used at the UW. It stands for Department of Vascular Imaging.

What schools offer training to become an interventional radiologist?

The Association of Vascular and Interventional Radiographers (AVIR) offers a section on its Web site about schools.
