Overall image quality and accuracy were not different between tsSOS-QISS and 2D-QISS, indicating that 3D tsSOS-QISS provides similar diagnostic value in patients with PAD to a standard commercially available 2D-QISS technique.
Figure 1 – 69-year-old man with PAD. Corresponding standard 2D-QISS MRA (A), 3D tsSOS-QISS MRA (B), and CTA (C) are shown. Total occlusion in the right distal superficial femoral artery and popliteal artery (yellow brackets) and significant stenosis in the left superficial femoral artery (yellow open arrows) are visualized. Stair-step artifacts can be seen on 2D-QISS (A, green brackets), which are not present on the corresponding 3D tsSOS-QISS (B, green brackets).
