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.
