MRI & MRA

Well, we were back into Western Neurological today for some additional follow-up testing and imaging. I had a contrast MRI done on my brain (which requires an injection of Gadolinium or a similar metallic compound -- cool stuff) and an MRA, also on my brain. For the uninitiated, here is the lowdown on MRAs:

Magnetic Resonance Angiography is the imaging of flowing blood in vessels using Magnetic Resonance Imaging (MRI). Magnetic Resonance Angiography (MRA) is used to generate images of the arteries in order to evaluate them for stenosis (abnormal narrowing), occlusion 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").
