can anyone help explain what my MRI/MRA scan results mean:While no definitive aneurysmal dilatation of the intracranial vasculature is evident, there is subtle suggestion of potential fenestration of the M1 segments bilaterally, left slightly more conspicuous than the right. There is no evident hemodynamically significant stenosis or high flow vascular malformation.
The dural venous sinuses demonstrate normal flow-voids. The visualized portions of the orbits, paranasal sinuses, mucosal spaces, and extracalvarial soft tissues are unremarkable as seen.
Impression: 1. Scattered nonspecific white matter T2/FLAIR signal hyperintensities present within the corona radiata and subcortical white matter without restricted diffusion, of indeterminant clinical significance. These findings can be seen in the setting of diabetes, hypertension, vasculitis, arteriolosclerosis, manifestations from chronic migraines, post infectious/posttraumatic etiology or other demyelinating state. 2. Suggested possible small fenestration of the bilateral M1 segments which is unable to be completely resolved on source data. Recommend further evaluation with CT angiogram for improved spatial resolution and clarification
