This prospective study is aimed to evaluate the
feasibility of 3D arterial spin label perfusion MRI
technique applied to the head and neck tumors. 17
enrolled patients underwent 3D ASL MR examinations with
three different PLD (1025ms, 1525ms, and 2525ms). SNRs
and blood flow (BF) values of tumors or lymph nodes were
analysis. The mean SNR of ASL with 1025ms was
significantly higher than the other two ASL sequences
(P<0.05). Mean BF values of the three ASL were not shown
significant difference (P=0.514). Tumors with different
histopathologic types had different BF values.
