Abstract

Objective: To investigate the accuracy of magnetic resonance imaging (MRI) in classifying sonographically indeterminate ovarian and adnexal masses.

Materials and methods: This was a retrospective cross-sectional study of the unenhanced pelvic MRI scans of 243 patients with a collective total of 336 adnexal and ovarian masses.

Results: Unenhanced MRI showed a sensitivity of 97.7%, a specificity of 86.4%, and an accuracy of 93.8%. The area under the ROC curve was 0.944 (95% CI: 0.913-0.974).

Conclusion: Our results show that an unenhanced MRI protocol can be used to classify adnexal masses, especially in clinical settings in which the intravenous administration of gadolinium-based contrast is not safe and should be avoided.

无增强磁共振成像评价超声不确定卵巢和附件肿块。

目的：探讨磁共振成像（MRI）对超声不确定卵巢及附件肿块分类的准确性。材料和方法：这是一项回顾性横断面研究，对243例共336例附件和卵巢肿块的未增强骨盆MRI扫描进行了回顾性研究。结果：未增强MRI的敏感性为97.7%，特异性为86.4%，准确率为93.8%。ROC曲线下面积为0.944 （95% CI: 0.913 ~ 0.974）。结论：我们的研究结果表明，非增强MRI方案可以用于对附件肿块进行分类，特别是在静脉注射钆造影剂不安全的临床环境中，应避免使用。
