This work investigates the sensitivity of partial volume correction methods to partial volume estimates using single-PLD PCASL. Random and biased errors were applied to partial volume estimates to simulate the variabilities in tissue segmentation. The results have indicated that current partial volume correction methods trade off accuracy in spatial variations in CBF against sensitivity to noise and errors in the partial volume estimates.
