- W2028849082 abstract "Clinical use of cardiac synchronized Magnetic Resonance Imaging has been limited because of long unacceptable acquisition times. BRISK (Block Regional Interpolation Scheme for k-space) is a rapid MRI technique, which employs temporal sparse sampling scheme that varies the sampling rate as a function of distance from the k-space center. Using combination of conventional segmentation and BRISK approach, a new rapid phase contrast cine approach named FAST was investigated. FAST technique samples contiguous regions of k-space using a segmentation factor, just as in conventional segmentation, with the difference that the segmentation factor (SF) is varied as a function of distance from the k-space center. FAST and BRISK can be performed in nearly equally scan times. Both retained excellent axial-velocity accuracy. However secondary velocities, which were two orders of magnitude lower than the primary, suffered from comparable inaccuracies and distortion in conventional segmentation, BRISK and FAST." @default.
