A technique of ICA-selective 3D TOF imaging using asymmetrically RF-shimmed Pre-saturation pulse is presented. By using 4-channel RF transmit coil, spatially asymmetric RF transmission is achieved. Then apply RF shimming parameter to Pre-saturation pulse, the saturation effect becomes spatially asymmetric, and achieved selectively visualize blood flow from each ICA. This technique provides high contrast between blood and brain parenchyma because it does not make TR longer.
