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

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.
