A non-invasive study which is conducted in a Magnetic Resonance Imager (MRI). The magnetic images are assembled by a computer to provide an image of the arteries in the head and neck. No contrast material is needed, but some patients may experience claustrophobia in the imager.
a procedure which is used to show up blood vessels in the body. It is used to diagnose conditions such as strokes.
A non-invasive study which is conducted in a Magnetic Resonance Imager (MRI). A computer utilizes a large magnet to provide an image of the arteries in the head and neck. Contrast material is usually not required.
A non-invasive imagining procedure of the cranial vessels.
MR image visualization of selected vascular structures, such as the Circle Of Willis or the carotid arteries.
An imaging technique which images flowing blood. [ Chapter 12
Permits imaging of the blood vessels in several parts of the body with diagnostic accuracy, similar to contrast angiography (the injection of x-ray dye directly into blood vessels, usually with a catheter inserted into the artery in the upper thigh), but at a fraction of the time and cost, and with none of the risk. The most frequent vessels studied include the brain and the neck.
A non-invasive imaging procedure of the blood vessels in the brain.
An imaging technique involving injection of a contrast dye into a blood vessel and using magnetic resonance techniques to create an image of the flowing blood through the vessel; often used to detect stenosis of the brain arteries inside the skull.
Magnetic Resonance Angiography is the imaging of blood vessels using Magnetic Resonance Imaging. Magnetic Resonance Angiography (MRA) is used to generate pictures of the arteries in order to evaluate them for stenosis (abnormal narrowing) or aneurysms (vessel wall dilatations, at risk of rupture). MRA is often used to evaluate the arteries of the neck and brain, the thoracic and abdominal aorta, the renal arteries, and the legs (called a "run-off").
