QUIPPS II • Saturate volume of interest RF GSS
QUIPPS II • Saturate volume of interest • Tag (invert) incoming blood RF GSS
QUIPPS II • Saturate volume of interest • Tag incoming blood • Kill bottom half of bolus RF GSS
QUIPPS II • Saturate volume of interest • Tag incoming blood • Kill bottom half of bolus • Wait for the rest to enter VOI • Image Read-out follows this pulse. Time it takes tagged bolus to reach VOI RF GSS
QUIPPS II • Perfusion image = control minus tagged • In tagged image, inverted spins from labeled blood decrease net magnetization
