WebQuiescent-interval single-shot (QISS) MRA is an ECG-gated inflow based technique that has been recently developed and Food and Drug Administration approved for peripheral arterial imaging. The sequence relies on a pre-saturation RF pulse to saturate the stationary tissues in the imaging slice, followed by a venous suppression pulse. WebPeripheral pulse gating cannot be used for heart imaging due to the long and unpredictable delay between cardiac contraction and arrival of the pulse wave to the finger. Peripheral pulse gating is commonly used for …
