本研究目的是对比单独使用扩散加权成像(DWI)和联合使用DWI及T2WI鉴别子宫肉瘤和良性子宫肌瘤。对103例患有子宫肌层肿瘤病人的103个病灶进行3T MR的T2WI和DWI分析,包括8例子宫肉瘤和95例良性子宫肌瘤。肿瘤在T2WI上的信号强度(SI)用肿瘤-子宫肌层对比率(TCR)进行定量,TCR由以下
The purpose of this study was to compare diffusion weighted imaging (DWI) alone and DWI and T2WI in the identification of uterine sarcoma and benign uterine fibroids. 103 lesions of 103 patients with myometrial tumors were subjected to 3T MR T2WI and DWI analysis, including 8 cases of uterine sarcoma and 95 cases of benign uterine fibroids. The signal intensity (SI) of the tumor on T2WI was quantified using tumor-myometrial contrast ratio (TCR), which was determined by the following
