Doctor suspects avm or narrowing of vessels in brain from mri. Have upcoming angiogram. Can they be wrong. I'm told this is strictly for exploration.?

Possibly. Mris are good screening tests for the avm. The final test is the angiogram. That is because this is a dynamic test, meaning that one can see the flow of the blood in the vessels. This will help with defining the anatomy of the vessels in the abnormality. As to whether an MRI may be wrong in diagnosing an avm, that is possible if the findings on the MRI are not clear.
MRI can have. False positive findings. Angiogram good idea. See radiologyinfo. Org to see about the agram.
Probably correct. Probably correct to do further studies for brain MRI findings. It is for evaluation (not "exploration"), and if there is a problem it may be addressed pro-actively if you agree with their recommendations.

Doctor suspects a avm or narrowing of vessels from mri. When I have an angiogram can they be wrong? The angiogram is for exploration.

Perhaps. The angiogram will be the gold standard to determine if you have an avm. It is better at visualizing this condition than the mri.
Yes. An MRI is a screening tool that can detect an avm. The cerebral angiogram provides a more detailed view of the vessels in the brain. It is true that there are suspicious areas seen on the MRI which are not true avm vessels. Conversely, there may be areas that may not be interpreted as avm, but become apparent on the angiogram.
