Abstract

MR angiography findings in 33 patients with moyamoya disease were compared with findings of conventional angiography. Steno-occlusive changes tend to be overestimated by three-dimensional time-of-flight (3D-TOF) on lower magnetic field units, but with newer 1.5 T units, 3D-TOF findings compare favourably with angiography. Moyamoya vessels are usually inadequately visualised on 3F-TOF, even at 1.-5 T. Magnitisation transfer and variable flip angle excitation significantly improved their visualisation.
