To evaluate the accuracy of transvaginal ultrasound (US) and gadolinium-enhanced magnetic resonance (MR) imaging in the assessment of the intratumoral structure of an adnexal mass.
The population comprised 82 patients with an adnexal mass who underwent both transvaginal US and gadolinium-enhanced MR imaging and had surgical confirmation. The findings from both modalities were compared retrospectively with those of surgery.
The sensitivity, specificity, and accuracy were 100%, 98%, and 99% with MR imaging and were 97%, 46%, and 68% with transvaginal US for the identification of solid tissue in the masses. Transvaginal US exhibited many (n = 25) false-positive results, especially in evaluation of lesions filled with blood or fatty tissue and small echogenic excrescences adherent to the wall, such as blood or fatty tissue.
Both transvaginal US and gadolinium-enhanced MR imaging were highly sensitive in identification of solid components within an adnexal mass. Gadolinium-enhanced MR imaging was specific, whereas transvaginal US was nonspecific.
评估经阴道超声（US）和钆增强磁共振（MR）成像在评估附件包块瘤内结构方面的准确性。
研究对象为82例患有附件包块的患者，这些患者均接受了经阴道超声和钆增强MR成像检查，并经手术证实。对两种检查方式的结果与手术结果进行回顾性比较。
在识别包块中的实性组织方面，MR成像的敏感性、特异性和准确性分别为100%、98%和99%，经阴道超声的敏感性、特异性和准确性分别为97%、46%和68%。经阴道超声出现了许多（n = 25）假阳性结果，尤其是在评估充满血液或脂肪组织的病变以及附着于壁上的小回声性赘生物（如血液或脂肪组织）时。
经阴道超声和钆增强MR成像在识别附件包块内的实性成分方面均具有高度敏感性。钆增强MR成像具有特异性，而经阴道超声则不具有特异性。
