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 more

Mri (Definition)

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

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 more

What can a CT scan of the brain catch that a brain MRI scan cannot?

What can a CT scan of the brain catch that a brain MRI scan cannot?

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 more

How can a brain MRI be done?

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
