The purpose of this study was to optimize a
pseudo-Continuous Arterial Spin Labeling (pCASL)
approach to quantify hepatic perfusion among healthy
volunteers. Six volunteers were examined using a 3T
Siemens scanner, pCASL sequences with 4 to 20
measurements in a plane orthogonal to portal vein with a
post label delay (PLD) of 600 ms were acquired. For two
subjects, four additional PLD (from 1000 to 1600 ms)
were tested. Results show a more robust estimation when
using 20 measurements. Furthermore the five PLD values
provided hepatic perfusion weighted differently by the
hepatic artery and the portal vein blood flows.
