Non-contrast enhanced ICA selective 3D TOF using cylinder excitation pre-sat pulse has a possibility which visualizes blood flow from left or right ICA like DSA. It requires one set of 3D TOF scan; non-labeled 3D TOF and ICA labeled 3D TOF, then scan time becomes two times longer than conventional 3D TOF scan. In this study, compressed sensing scheme was applied to reducing the scan time of selective 3D TOF. Proposed method uses similarity between 3D TOF images with and without pre-sat pulse. This realizes only 1 minutes’ additional ICA selective 3D TOF scan to conventional 3D TOF scan.
