对374例临床疑诊附件包块的女性患者进行1.5T磁共振（MR）成像，评价其在诊断子宫内膜囊肿及与其他妇科包块鉴别诊断中的价值。 当T1加权像上呈高信号的囊肿在T2加权像上表现为均匀高信号时，提示诊断为子宫内膜囊肿。 当T1加权像上呈高信号的囊肿在T2加权像上呈低信号（阴影）或当病变在T1加权像上由多个高信号囊肿组成（多重性）时，无论T2加权像上的信号强度如何，都可以做出明确的诊断。 在293例患者中进行了手术，并在354处病变中获得了确认。 MR成像能够准确诊断86例子宫内膜囊肿中的77例，并在268例其他妇科肿块中排除了263例子宫内膜囊肿伴或不伴内出血。 总的诊断敏感性、特异性和准确性分别为90%、98%和96%。 磁共振成像似乎是一个可接受的诊断测试，临床决策可以根据选择治疗。
The value of 1.5-T magnetic resonance (MR) imaging in diagnosing endometrial cysts and differentiating them from other gynecologic masses was prospectively evaluated in 374 female patients with clinically suspected adnexal masses. A suggestive diagnosis of endometrial cyst was made when a cyst that was hyperintense on T1-weighted images exhibited homogeneous hyperintensity on T2-weighted images. A definitive diagnosis was made when a cyst that was hyperintense on T1-weighted images exhibited hypointense signal on T2-weighted images (shading) or when the lesion consisted of multiple hyperintense cysts on T1-weighted images (multiplicity) regardless of the signal intensity on T2-weighted images. Surgery was performed in 293 patients, and confirmation was obtained in 354 lesions. MR imaging enabled accurate diagnosis of 77 of 86 endometrial cysts and exclusion of the diagnosis of endometrial cyst in 263 of 268 other gynecologic masses with or without internal hemorrhage. The overall diagnostic sensitivity, specificity, and accuracy were 90%, 98%, 96%, respectively. MR imaging seems to be an acceptable diagnostic test on which clinical decisions can be based in selecting treatment.
