The aim was to determine the utility of diffusion-weighted magnetic resonance imaging (DW MRI) and apparent diffusion coefficient (ADC) measurements in differentiation of endometrioma and hemorrhagic ovarian cyst. A total of 24 female patients who underwent pelvic MRI with an initial diagnosis of ovarian cyst were included in the study. The final diagnosis was endometrioma in 12 patients and hemorrhagic ovarian cyst in 12 patients. We observed significantly lower ADC values in endometriomas compared with hemorrhagic ovarian cysts in all b values. DW MRI with quantitative ADC measurements can be used for differentiation of endometrioma from hemorrhagic ovarian cysts.
目的是确定扩散加权磁共振成像（DW MRI）和表观扩散系数（ADC）测量在鉴别子宫内膜瘤和出血性卵巢囊肿中的效用。共有24例初步诊断为卵巢囊肿并接受盆腔MRI检查的女性患者纳入本研究。最终诊断为12例子宫内膜瘤和12例出血性卵巢囊肿。我们观察到，在所有b值下，子宫内膜瘤的ADC值均显著低于出血性卵巢囊肿。具有定量ADC测量的DW MRI可用于鉴别子宫内膜瘤和出血性卵巢囊肿。
