In this present study, by applying the special mouse coil(4 channel), IVIM-DWI with 14 b-factors(0~1000s/mm2) was successfully conducted on nude mice with different radio-sensitive NPC xenografts(CNE-1 and CNE-2) during the course of fractional radiations. The IVIM-DWI parameters of xenografts were found to change characteristically after fractional radiations and were significantly different between different radio-sensitive NPC xenografts, and their corresponding changes also behaved significant correlations with the pathological features of NPC xenografts. Thus, it is suggested IVIM-DWI parameters be valuable in evaluating the micro-structures and radio-sensitivity of NPC xenografts.
