Abstract
Sixtyfive consecutive patients 48 men with suspected NPC were examined using a 30T MR system Diffusionweighted imaging DWI was performed with 13 b values range 0–800 s/mm2 We regarded the result of endoscopy and biopsy as the gold standard for detection D D and f were compared between patients with primary NPC and enlarged adenoidsIVIM DWI was successful in 37 of 40 NPC and 23 of 25 enlarged adenoids cases D P = 0001 and f P 00001 were significantly lower in patients with NPC than in patients with enlarged adenoids whereas D was significantly higher P 00001 However the ADC was not significantly different between the two groups P 005 The area under the ROC curve AUC for D was 0849 and was significantly larger than that for ADC P 005
