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.
