In this study, we aimed to investigate 3D pcASL with multiple PLDs in evaluating subtypes of parotid gland tumors. By quantitatively measuring tumor blood flow (TBF) and comparing the values within and between subgroups, we found 3D pcASL with multiple PLDs can differentiate parotid gland tumors and reflect changes of TBF. With these findings, 3D pcASL MRI, especially with short PLD was suggested to evaluate patients with parotid gland tumors in routine clinical practice.
