Interventional radiology/Image-guided therapy

What is interventional radiology?

Interventional radiology is a subspecialty of imaging that uses image guidance techniques to perform minimally invasive procedures, which often removes or lessens the need for surgery. Image-guided therapy treats conditions inside the body from outside the body, by using imaging techniques (i.e., CT scannersultrasound scanners) to insert small instruments or tools, such as catheters or wires. The images provide a road map that allows the interventional radiologist to guide these instruments.

Sometimes these techniques can be used instead of surgery. X-rays and other imaging tests, like ultrasound, can help doctors see inside the body. When small tools, such as tubes and wires, are used with imaging exams, some conditions can be treated with minimally invasive surgery. It may take only a few small cuts to reach areas inside the body that need treatment or repair. Often, no cuts are needed at all. That can mean a shorter stay in the hospital and faster recovery.

Who is the interventional radiologist?

The interventional radiologists at Children's Hospital of Wisconsin are among a select group of physicians, fewer than 100 nationwide, who specialize in pediatrics. They have additional years of fellowship training and continue to learn the most innovative and effective techniques. Performing more than 3,000 cases a year, our volume is in the top six for pediatric hospitals nationally.

Interventional radiologists are involved in the treatment of patients and the diagnosis of disease. Pediatric interventional radiologists are doctors who can find and treat acute and chronic conditions with the help of X-ray and other imaging tests. Interventional radiologists work closely with other physicians and play an important role on the treatment team.

Interventional radiologists perform a variety of procedures.

Our specialists

What is the interventional radiology clinic?

The interventional radiology clinic is where you or your child will meet the interventional radiologist and discuss your situation in detail. Care is provided in the clinic before and after your procedure. Depending on your needs, your child's images are reviewed, your child will be examined or will have an ultrasound performed, all in one visit. You also can discuss and arrange treatment at this time.

Patients in our clinic may have a variety of conditions, or need a variety of procedures, including:

Day of procedure

  • You and your child will arrive in Day Surgery at the hospital 2 hours before your scheduled procedure. Your child may have lab work and a physical exam before the procedure while you will be asked to provide a medical history.
  • A nurse will then take you and your child to Interventional Radiology, where the pediatric interventional radiologist and pediatric anesthesiologist will answer questions and complete consent forms. Our nursing team will introduce themselves and provide a family pager. A nurse will update you during the procedure and notify you when the procedure is finished.
  • After the procedure, the pediatric interventional radiologist will meet you in the 3rd floor surgical family waiting area to discuss the results of the procedure and expected outcomes.

Follow-up phone call

The clinic nurse will call the you 24 to 48 hours after the procedure to check on progress, answer questions, and address any concerns. Your feedback is important to us. It helps us provide the best quality care.

Follow-up clinic care

Patients generally are asked to return to the clinic several times after the procedure. The clinic nurse schedules these appointments following each procedure.
