We have developed a 3D-QISS technique for high
resolution (through-plane: 0.3 mm), non-enhanced
peripheral MRA. The proposed method is a modification of
the quiescent-interval single-shot (QISS) technique with
a 3D TrueFISP readout and spectral selection attenuated
inversion recovery (SPAIR) for fat suppression. QISS3D
demonstrated excellent image quality, improved venous
suppression, and superior signal-to-noise ratios.
