No reports have focused on the evaluation of tumor blood
flow (TBF) using pseudo-continuous arterial spin
labeling (pcASL) in the salivary gland tumor. However,
we demonstrated a significant difference in TBF between
a salivary gland Warthin tumor and pleomorphic adenoma.
The significant correlation between TBF and the tumor
vascular density (
p
<
0.01, r
s
=
0.93) suggests that precise evaluation of the tumor
perfusion state could be accomplished using pcASL. Thus,
differential diagnosis of a salivary gland tumor may be
possible to some extent even without the use of contrast
material.
