QISS ontrast enhanced Angiography QISS provides: • an “easy-to-handle approach for imaging peripheral arteries with little requirement for further adjustments” 1 . Cor Tra 2 • non-CE peripheral MRA for patients with renal insufficiencies at comparable accuracy to contrast enhanced MRA 2 .

The image contrast is then generated using an in-plane ECG saturation pulse to suppress the background tissue. This tracking saturation pulse is used to suppress venous Arterial Flow signal prior to the quiescent inflow period.

Use new electrodes every single time. • If one of the leads does not provide a sufficient signal, change to a single ECG lead in the Physiological Display dialog window.

If necessary, pull the cables through the neckline of the patient’s shirt. • Position the necessary coils on the patient. • Typically, the peripheral angio coil for the extremities and one or more body coils and the spine coil for the abdominal region are used. Center the light localizer to max. 1/2 FoV above the feet. • • There is a decision point for the patients’ heart rate – the only difference is the iPAT factor (p3 for short RR intervals < 800ms; p2 for longer RR intervals > 800ms); this reduces the readout time for faster heart rates, so that data acquisition is still within a single heartbeat. • However even if the heart rate varies, for example and the next R-wave comes along whilst we are still acquiring during the readout, it doesn’t matter from an imaging perspective, it just means that the next heart beat is skipped, so the overall acquisition time will be longer e.g. if only every second heartbeat is acquired, then 100 heartbeats to acquire 50 slices, instead of 50 which are needed.
