The
alternating TR (ATR) balanced SSFP technique has proven to be useful for
suppression of unwanted species while extending the TR interval available for
increased spatial resolution.
Ultra-high 0.29 mm isotropic resolution has been achieved by extending
the performance of the multi-acquisition fat-water separation ATR SSFP
sequence through the implementation of a 3D radial trajectory. Applications in cartilage assessment and
vasculature imaging are demonstrated in the knee joint.
