T2-weighted
dark blood prepared TSE sequences are commonly used to image cardiac
pathology. These methods often suffer from motion artifacts due to their long
acquisition times. Here we apply a new, fast, high SNR, dark blood prepared
segmented TrueFISP sequence (HEFEWEIZEN) for cardiac imaging in which some TR
blocks are replaced by spatially selective saturation pulses for out-of-slice
signals. This directionally suppresses bright blood flow (>65%) in the
cardiac ventricles with some stationary tissue signal suppression offering a
potential application to cardiac imaging.
