对17例超声提示盆腔肿块的孕妇进行了磁共振（MR）成像的价值评估。47%（17例中的8例）的磁共振成像信号显示病变特征得到改善，包括4例卵巢成熟囊性畸胎瘤中的2例，3例子宫肌瘤，1例卵巢实体瘤，1例子宫内膜瘤，1例被误认为卵巢囊性肿块的膀胱扩张。3例卵巢囊腺瘤和2例单纯性卵巢囊肿的mri和超声诊断均准确。2例单纯性卵巢囊肿被误诊为复杂囊性肿块，1例畸胎瘤被误诊为单纯性囊肿。骨盆肿块的起源（13个在卵巢，3个在子宫，1个膨胀的膀胱）在100%（17个中的17个）的磁共振图像上准确确定，而在71%（17个中的12个）的超声图像上准确确定。在三个病例中，磁共振成像的结果导致手术取消，而手术本应仅根据超声结果进行。磁共振成像是一个有价值的补充超声术前评估盆腔肿块在孕妇。
The value of magnetic resonance (MR) imaging was assessed for 17 pregnant patients with sonograms suggestive of a pelvic mass. The MR imaging signal features improved lesion characterization in 47% (eight of 17) of cases, including two of four mature cystic teratomas of the ovary, three uterine fibroids, one solid ovarian tumor, one endometrioma, and a distended urinary bladder that had been mistaken for an ovarian cystic mass. Both MR imaging and sonography were accurate for the characterization of three ovarian cystadenomas and two simple ovarian cysts. On both MR images and sonograms, two simple ovarian cysts were incorrectly diagnosed as complex cystic masses and one teratoma was incorrectly diagnosed as a simple cyst. The origin of the pelvic mass (13 in the ovary, three in the uterus, and one distended urinary bladder) was accurately determined on 100% (17 of 17) of the MR images versus 71% (12 of 17) of the sonograms. In three cases, the results of MR imaging led to cancellation of surgery, which would have proceeded on the basis of the sonographic results alone. MR imaging is a valuable complement to sonography for preoperative evaluation of pelvic masses in pregnant patients.
