Abstract：Objective To explore the clinical value of CT/MRI image fusion technique in the delineating of gross tumor volume in intensity-modulated radiotherapy for nasal pharyngeal cancer (NPC). Methods 50 patients confirmed as NPC by pathology were treated with intensity-modulated radiotherapy. The gross tumor volumes (GTVs) were delineated under CT images and CT/MRI fusion images respectively. Then the differences of GTVs between CT group and CT/MRI group were compared. Results The average GTVs of CT group and CT/MRI group were (29.18±19.12) cm3 and (33.57±20.63) cm3 respectively, and the differences were significant (P<0.05). Comparing to the T stage, the two groups had obvious differences of GTVs on T1, T2 and T3 stage (P<0.05), but not obvious on T4 stage (P>0.05).Conclusion CT/MRI image fusion technology which combines CT and MRI, is helpful to improve the accuracy of delineating gross tumor volume in radiotherapy for NPC.
