Liver lesion detection : Comparison of different flip angle and delay time

Detection of liver lesion remains challenge since the contrast to noise ratio is always changing after intravenous bolus injection of Gd-BOPTA between lesion and liver tissue. The purpose of the study was to compare the lesion-to-liver CNR for different schemes using different flip angle and delay time. The results shows that the protocol of 60min FA10°could be used as the preferred scanning parameter, it could also be used to save the scan time.
