1 二维超声在卵巢恶性肿瘤诊断的价值超声检查作为一种无损检查方法开始于60年代。早在1964年 Sunder 首次描述了卵巢肿瘤的声像图特征,但由于受仪器分辨力的影响,直到80年代初期才应用于区别卵巢良恶性肿瘤。Comphell 等报道超声结合卵巢恶性肿瘤病理学特征区别卵巢良恶性肿瘤的特异性高达97.7%,但阳性预测值仅1.5%左右。高频阴道内超声的临床应用,大大提高了超声图像的分辨力,其分辨能力从腹部超声的1～2mm 提高到0.1～0.2mm。在此基础上建立了超声卵巢良恶性肿瘤区别评分法(表1)。采用该评分法诊断卵巢恶性肿瘤的敏感性100%,特异性83%。而 Kentucky 大学的普查结果显示经阴道超声在卵巢恶性肿瘤的早期诊断方面也有一定的价值。提示超声尤其经阴道超声不仅在卵巢恶
A two-dimensional ultrasound in the diagnosis of ovarian cancer Value of ultrasound as a non-destructive examination method began in the 60’s. As early as 1964 Sunder first described the ovarian tumor sonographic features, but due to the resolution of the instrument, until the early 80s should be used to distinguish between benign and malignant tumors of the ovary. Comphell et al reported that the specificity of ultrasound combined with pathological features of ovarian cancer differentiated benign and malignant ovarian tumors up to 97.7%, but the positive predictive value was only about 1.5%. The clinical application of high frequency intravaginal ultrasound greatly improves the resolution of ultrasound images, and its resolving power is increased from 1 ~ 2mm of abdominal ultrasound to 0.1 ~ 0.2mm. On this basis, the establishment of a distinction between benign and malignant tumors of ultrasound score (Table 1). The use of the scoring method for the diagnosis of ovarian cancer sensitivity 100%, specificity 83%. The University of Kentucky census results show that transvaginal ultrasound in the early diagnosis of ovarian cancer also has some value. Prompted ultrasound, especially transvaginal ultrasound not only in the ovary evil
