In a prospective study, 32 women with suspected pelvic masses at physical examination underwent both endovaginal ultrasound (US) and magnetic resonance (MR) imaging to compare their ability in diagnosis of adnexal masses. Criteria for the diagnosis of various types of adnexal masses with MR imaging and endovaginal US were prospectively defined, and the ability of either modality to allow a specific diagnosis was assessed. For each modality, measures of sensitivity, specificity, and accuracy were obtained. Results indicated higher diagnostic capability of endovaginal US for simple cysts (five of five), hemorrhagic cysts (eight of nine), endometriomas (nine of 14), and ovarian carcinomas (three of three). MR imaging demonstrated higher diagnostic capability for dermoids (three of three). MR imaging and endovaginal US showed equal diagnostic capability for pedunculated fibroids (two of two). For all masses, observers, and observations, the overall sensitivity of endovaginal US was 76% versus 49% for MR imaging, and the overall accuracy of endovaginal US was 83% versus 70% for MR imaging. The authors suggest that endovaginal US is a better modality than MR imaging for the assessment of suspected pelvic masses.
在一项前瞻性研究中，32名在体格检查时怀疑有盆腔肿块的女性接受了经阴道超声（US）和磁共振（MR）成像检查，以比较它们对附件肿块的诊断能力。前瞻性地定义了用MR成像和经阴道超声诊断各种类型附件肿块的标准，并评估了两种检查方法进行特异性诊断的能力。对于每种检查方法，均获得了敏感性、特异性和准确性的测量值。结果表明，经阴道超声对单纯囊肿（5例中的5例）、出血性囊肿（9例中的8例）、子宫内膜瘤（14例中的9例）和卵巢癌（3例中的3例）具有更高的诊断能力。MR成像对皮样囊肿（3例中的3例）显示出更高的诊断能力。MR成像和经阴道超声对带蒂肌瘤（2例中的2例）显示出相同的诊断能力。对于所有肿块、观察者和观察结果，经阴道超声的总体敏感性为76%，而MR成像为49%；经阴道超声的总体准确性为83%，而MR成像为70%。作者认为，对于疑似盆腔肿块的评估，经阴道超声是比MR成像更好的检查方法。
