My mother recently had an MRI done for her constant migraines with auras and loss of vision at times. Can you help us interpret the findings and see if there are other tests that she might need done or what might be going on with her? Her migraines are more intense and common in the past two weeks. Findings: Subarachnoid spaces and ventricles are unremearkable. There are tiny periventricular and subcortical foci of T2 weighted hyperintensity which appear nonspecific and my represent white matter ischemic or microvascular changes.
