The Findings of MRI and Transcranial Doppler Sonography in Three Cases of Moyamoya Disease

The confirmatory diagnosis of Moyamoya disease has been obtained by invasive angiographic examination. We report the results of MRI and transcranial doppler sonography of three cases ol Moyamoya disease, which ws disgnosed by clinical and angiography. We think that the diagnosis of Moyamoya disease can be made by noninvasive MRI and transcranial doppler sonography without conventional invasive angiography.
