What Can A Mra Detect That A Brain Mri Cannot Detect
Vascular disease: Mra looks at moving blood in the arteries of the brain and can help in the diagnosis of vascular narrowing from atherosclerosis, or anerysms, and arteriovenous malformations (avm). Though an MRI may detect large aneurysms and if contrast is given suggest avm, mra is much more sensitive than MRI when investigating vascular anatomy. Mra does have its limits, small aneurysms can't be detected. ...Read moreSee 2 more doctor answers
Mri or magnetic resonance imaging is one of the more recently developed imaging modalities available to physicians. It uses powerful magnets to generate images. There is no ionizing radiation which is a major advantage over many other modalities. Mri is the best imaging exam that we have for most soft tissue and joint related problems. There are radiologists ...Read more

Had brain mri/wcontrast.Small spot rt side seen by neuro said hypertension maybe but no ms.Should i be worried.Taking 81mg aspirin now mra of neck nex?
Small white spot: A single small white spot should not be cause for concern. It can be caused by high blood pressure. Since you have high blood pressure, it makes sense to use a little aspirin. We see white spots in 50% of our brain MRI's up here. If you also have headaches, it is reasonable to have the MRA test. Otherwise I am not sure why this test was ordered. ...Read moreSee 1 more doctor answer
Also, very fast!: Agree with excellent answer above. Additionally, ct scans have the advantage of being much faster than MRI scans, and they are much more widely available- if you come into a small hospital's er at 3 in the morning, they will likely be able to do a ct immediately, while an MRI might wait until the next morning (if it is available at all!). ...Read moreSee 2 more doctor answers
Having throbbing vessels, pressure and faint feeling in back of head. Cant sit up. Had mri/mra of brain and neck. Any other tests?
MRI: You will be asked to rest on your back and not move your head during the mri. You will be moved into the scanner. The MRI machine has enormously powerful magnets which will orient hydrogen molecules into a single direction. When a when the magnet energy is changed, the hydrogen atoms give off energy which will be picked up by the computer. ...Read more
NUMEROUS ITEMS: Brain MRI is quite precise and allows very discrete images of large and small strokes, areas of old or new bleeding, abnormal blood vessels and tumors, congenital brain malformations, focal and diffuse areas of inflammation, such as infections or multiple sclerosis or vasculitis, etc. ...Read more
