Minimally Invasive, Image-Guided Treatments & Procedures Interventional Radiology Delivers.
Reduced Risk—Less Pain—Shorter Recovery Times
Cutting-Edge, 21st Century Medicine Interventional Radiology is Synonymous with Modern Medicine

Who We Are

The Interventional & Vascular Institute is one of the three divisions operated under UPSVIS’s Dr. Christopher Mehall. While the practice’s clinic is located at 717 W. Washington Street in Marquette, all interventional procedures are performed at UPHS-Marquette that is adjacent to the clinic. Dr. Mehall developed the IR program in 1997 when he was the first fellowship trained IR in the UP. He brought several new procedures and services to UPHS that patients at one time would have to travel to other hospitals downstate or to Wisconsin for to recieve.

Interventional radiology uses cutting-edge technology to diagnose and treat patients using minimally-invasive procedures.

What We Offer

Interventional radiology is one of the fastest growing areas of medicine and is one of the most recently recognized medical specialties by the American Board of Medical Specialties and the American Medical Association. Interventional radiologists specialize in minimally invasive, targeted treatments, performed under guidance of medical imaging. They use their expertise in reading medical imaging studies, such as X-ray, CAT scan, MRI and Ultrasound, to guide very small instruments, such as catheters, through the skin and blood vessels, often eliminating the need for open surgery.

The advantages of Interventional Radiology?

  • Most procedures are performed on an outpatient basis or will require only a very short hospital stay.
  • Most procedures are done with mild sedation. General anesthetic is usually not required.
  • Complications, pain, and recovery time are often greatly reduced as compared with traditional surgical treatments.

Interventional radiologists work with several physicians at UPHS treating brain and stroke issues

Our very own Dr. Mehall was shown on the local Ask the Doctor show along with a few other members of the UPHS Neuroscience team discussing Brain and Stroke Issues. Great topics and discussions included Aneurysms, Brain Tumors, Dementia, Parkinson’s, along with Carotid Stenosis, Spinal Stenosis and Treatment of Chronic Neck and Back pain.


Having the tests provided at the time of appointment and in the same area was very helpful.

The staff is very nice.

Dr. Mehall and all of his staff were just so happy, helpful, and caring.
