What is interventional radiology (IR)?

Interventional radiology refers to a specialized area of radiology that uses X-ray, fluoroscopy, ultrasound and other imaging technologies to treat a variety of medical conditions without surgery. These minimally invasive procedures include biopsies, inserting venous access devices, draining fluids and opening narrowed blood vessels.

Before Your Exam

A nurse will call you the day before your procedure to review any preparations for your scheduled procedure. During this time, you should also arrange for an adult to be present for the post-procedure instructions, to take you home and to remain with you after immediate discharge. For your safety, your procedure may be cancelled if these arrangements are not made.

On the day of your procedure, please arrive at least two hours before your appointment and bring a list of your medications. You will be escorted to our pre-procedural area and then change into a gown. If needed, the clinical team will draw blood for lab work. The interventional radiologist will discuss the procedure with you. An anesthesiologist will also speak to you if sedation is required.

What to Expect

Our team will escort you to a procedure suite and make sure you are as comfortable as possible.

An anesthesiologist will monitor your sedation throughout the entire procedure.

When finished, you will be transported back to the recovery room.

Exam times vary greatly, depending on the type of procedure.

After Your Exam

A caregiver must drive you home from the hospital on the day of your procedure after you have completed the recovery period. They do not have to stay during the exam. A phone number can be exchanged with the staff in the Radiology Recovery Unit to contact them at the time of your discharge. Results from the procedure will be sent to your ordering physician.
