A highly accelerated 4D flow MRI method with a high tempospatial resolution has been validated in healthy volunteers by comparing to the conventional method. The proposed method been demonstrated to be very promising for imaging the patients with intracranial aneurysms, by achieving an isotropic resolution of 1.3mm and a temporal resolution of 26ms within a 5-minute scan time (R=12).
