Abstract: Objective To investigate the effect of DWI in diagnosing ovarian carcinoma .Methods MRI and DWI were performed in 33 patients with ovarian carcinoma and 23 patients with benign ovarian tumor proved by pathology ,respectively .ADC values of the cystic components and the solid components were respectively measured in ovarian carcinoma and benign ovarian tumor .Results The mean ADC value of solid component in ovarian carcinoma was (1 .68 ± 0 .37)× 10-3 mm2/s ,which was significantly lower than that of solid component in benign tumor [(3 .51 ± 0 .53) × 10-3 mm2/s] .There was no significant statistical difference between ovarian car‐cinoma and benign tumor in ADC value of cystic component [(5 .34 ± 0 .54)× 10-3 mm2/s vs (5 .89 ± 0 .37)× 10-3 mm2/s] .Conclu‐sion DWI is useful for diagnosis and differential diagnosis of ovarian carcinoma quantitatively .
