CT OR MRI PERFUSION

WHAT IS CT OR MRI PERFUSION?

Perfusion means the injection of fluid into a blood vessel to reach an organ in the body.  CT or MRI perfusion uses a CT (computerized tomography) or MRI (magnetic resonance imaging) scan to provide images, or a “map” of the part of the brain that is injured during a stroke, along with the area around it.

CT or MRI perfusion is a tool that helps doctors determine what kind of stroke the patient has had, and the therapies that will help the most: By viewing the injured areas along with the healthy areas, doctors can help make care decisions that prevent further damage.

HOW DOES IT WORK?

During CT or MRI perfusion, the doctor will inject a “contrast medium.” This allows our stroke team to see how the blood is flowing to the brain, along with any clots or blockages.

A special computer program will then calculate how fast the blood is moving through the brain. This program will help our stroke specialists decide if further treatment is needed, such as an interventional thrombectomy which can help dissolve a clot.

During an interventional thrombectomy, the doctor will inject special “clot-busting” medications to the blood vessels supplying the brain. The medications are given via a catheter, which is usually inserted through an artery in the leg or groin.

WHAT ARE THE BENEFITS OF CT OR MRI PERFUSION?

CT or MRI perfusion:

  • Provides our stroke team with a precise map of the stroke location and severity
  • Shows healthy brain tissue along with any damaged areas
  • Helps us determine what treatment options are best, even when we are unsure of the time of stroke
