Tumor extent assessment of NPC is critical for delineating the radio-therapeutic target region. We aimed to investigate the use of the fusion images of fat suppressed (FS)-T2 with arterial spin labeling (ASL) in measuring the volume of NPC. Two observers measured the volume of 21 untreated NPC using FS-T2, FS-T2/ASL (with PLD=1.0, 1.5 and 2.0s) fusion images and enhanced-T1WI separately. Compared to those obtained using FS-T2 alone, measurements made using FS-T2/ASL were more consistent with those made using enhanced-T1WI. The FS-T2/ASL fusion image has the potential to be an alternative to enhanced-T1WI, when contrast administration can not be performed.
