We have proposed vessel - selective 3D volumetric non -contrast time- resolved MRA technique termed Contrast inherent inflow enhanced multi phase angiography ( v-sel CINEMA ). In this study the vessel selective PULSER preparation module was combined with a 4D T1 TFE readout that has previously been shown to generate time resolved MRA in healthy volunteers as well as in patients carrying cerebrovascular abnormalities. vsCINEMA could extract the blood flow in the whole brain at an interval of about 200 ms with a high degree of vessel specificity and showed good agreement compared to TOF-MRA and MR-DSA . vsCINEMA allows visualizing the dynamics of cerebral blood flow with high spatial and temporal resolutions. Patients carrying cerebrovascular pathologies such as AVM and moyamoya disease are good candidates for further investigations.
