What is Interventional Radiology?

Interventional radiology is a medical subspecialty dedicated to imaging-guided procedures for diagnostic and therapeutic purposes. Interventional radiologists diagnose and treat conditions using tiny instruments and are assisted by specially trained technologists. Interventional procedures can provide an alternative to surgery. Interventional procedures are less invasive involving very small incisions (less pain, less scarring) so patients find interventional procedures more tolerable than surgery. Many interventional procedures require only a local anesthetic; however, conscious / IV sedation is sometimes necessary depending on the procedure. Interventional procedures often have fewer complications than surgery, require shorter hospital stays and less nursing care. These procedures usually cost less than their surgical alternatives too.


You should not eat anything after the midnight the night before your interventional procedure. Only have small sips of clear liquids after midnight. There may be restrictions on some of your medications. You should plan to have someone to drive you home after your recovery time of 2-6 hours, depending on the procedure performed.

What can I expect during the procedures?

Your specific procedure will be explained to you before obtaining your informed, written consent. You will have an IV started and usually have some blood drawn for lab work. The procedure site will be sterilized and a local anesthetic will be used at the along with mild IV sedation to make you comfortable.

What can I expect after the procedure?

After your procedure, you will go to a recovery area for 2-6 hrs., then, you will be sent home with discharge instructions specific to your procedure. You will need someone to drive you home. After interpreting the images from your exam, a radiologist will write a report for your physician.  Your physician will discuss the results with you.
