Feminine Pelvic Lesions:Diffusion-weighted MR Imaging / 实用放射学杂志

ABSTRACT

Objective To investigate the value of diffusion-weighted imaging(DWI) in diagnosing the feminine pelvic lesions.Methods Conventional MRI and DWI with b value of 0 and 1000 s/mm2 respectively were performed in 135 feminine patients with pelvic lesions. Apparent diffusion coefficient (ADC) values of the lesions were measured. Contrast-enhancement MR imaging was performed in 16 patients.Results The average ADC values were (0.90?0.10)?10-3mm2/s in uterine malignant lesions (43 cases),(0.12?0.09)?10-3mm2/s in uterine benign lesions ( 24 cases ) , ( 0.98?0.11 )?10-3mm2/s in adnexal malignant diseases ( 34 cases ) and ( 2.25?0.12)?10-3mm2/s in adnexal benign ones(34 cases), respectively.There were significant differences between malignant and benign groups(P
