  • Interventional Radiology

    Interventional radiologists (IRs) use their expertise in reading X-rays, ultrasound and other medical images to guide small instruments such as catheters.


These procedures are typically much less invasive and much less costly than traditional surgery. Northern Arizona Radiology offers a variety of interventional procedures in the convenience of an outpatient setting from Venacure for varicose veins to breast biopsies and joint and spine injections for pain management. Interventional procedures requiring hospitalization are performed by Northern Arizona Radiology physicians at Flagstaff Medical Center.

Common Uses of Interventional Radiology

An X-ray exam of the arteries and veins to diagnose blockages and other blood vessel problems.
Balloon Angioplasty and Stenting
Opens blocked or narrowed blood vessels by inserting a very small balloon into the vessel and inflating it.  A metallic stent may be deployed to keep the vessel open longer.
Involves the injection of contrast agents into a joint using imaging guidance.  Often used in conjunction with MRI, CT or plain X-rays to enhance visualization of structures inside the joint.  Medications may also be injected into the joint for pain management.
Central Venous Access
Insertion of a tube to allow patients to receive medication or nutrients directly into the blood stream or so blood can be drawn.
Pain Management
Imaging guidance is useful for the  precise targeting of body parts to be injected with medication.     Common procedures using imaging guidance include Epidural Steroid Injections for back pain or sciatica, spine facet injections, and injections of joints such as the shoulder, hip, elbow, and ankle.
Delivery of contrast into the spinal canal using X-ray guidance. Used in conjunction with CT scanning to evaluate for narrowing of the spinal canal and impingement of the nerves exiting the spinal canal.
Hemodialysis Access Maintenance
Use of angioplasty or thrombolysis to open blocked grafts for hemodialysis.
Needle Biopsy
Diagnostic test for breast, lung and other cancers; an alternative to surgical biopsy.
Delivery of clotting agents directly to an area that is bleeding or to block blood flow to an aneurysm or a mass
