1. Prolong the arterio-venous (AV) window by venous compression. Use a midfemoral compression with a pressure cuff at 50-60 mmHg. A normal blood pressure cuff without the metal parts usually works fine.
2. Use centric k-space filling if available. If ontrast appears in the veins, this will not add much to the contrast in the image as at that moment the periferal lines of k-space are scanned, which mostly add to he resolution in the image.
3. In patients with critical ischemia do a biphasic examination to concentrate first on lower leg and feet.
