Overview

A cerebral angiogram or magnetic resonance angiogram (MRA) is usually requested as lesions can go undetected in an MRI. If a lesion is discernible via angiogram in the same location as in the MRI, then an arteriovenous malformation (AVM) becomes the primary concern.

Magnetic Resonance Angiography

• The low-flow property of cerebral cavernous malformation (CCM) lesions makes it difficult to be seen angiographically.
• If a lesion is discernible via angiogram in the same location as in the magnetic resonance imaging (MRI), then an arteriovenous malformation (AVM) becomes the primary concern.
