目的：探讨磁共振扩散加权成像ADC值在鉴别诊断女性盆腔良恶性肿瘤的价值。方法回顾性分析42例经手术病理证实女性盆腔肿瘤患者的MRI资料，分析肿瘤DWI信号强度及ADC值的差异。结果女性盆腔良性肿瘤病变DWI信号表现不同，可以呈等、较高或高信号，恶性肿瘤性病变在DWI上大部分表现为高信号。良性病变平均ADC值为(1.55±0.48)×10-3mm2/s，恶性病变平均ADC值为(1.23±0.37)×10-3mm2/s，恶性病变的ADC低于良性现变(P=0.023)。结论磁共振扩散加权成像(DWI)信号和ADC值可为良恶性肿瘤的鉴别诊断提供依据。

Objective To explore the value of ADC in the differential diagnosis between benign and malignant tumors in the female pelvis. Methods DWI sequence was performed in 42 females with pelvic tumors proved by histopathology. The signal intensity on DWI and ADC values for tumors were analyzed. Results Benign tumors showed iso-or hyper-signal intensity, while most malignant tumors showed hyper-signal intensity on DWI sequence. The mean ADC values for benign and malignant tumors were (1.55±0.48)×10-3mm2/s and (1.23±0.37)×10-3mm2/s, respectively. The difference of ADC value between two groups were statistically significant(P=0.023). Conclusion The signal intensity on DWI and ADC vale provide valuable information for differential diagnosis for pelvic tumors in female.
