目的:评价经阴道超声在筛检囊性畸眙瘤及鉴别囊性畸胎瘤与其他卵巢肿瘤中的作用。方法:对376名未绝经非妊娠妇女在剖腹手术或行腹腔镜手术前1周行经阴道超声检查。将局限的或弥漫的强回声影象作为囊性畸胎瘤的超声持征性表现。同时将超声诊断与外科手术及病理所见进行比较。结果:超声下可见卵巢共659个,其筛检囊性畸胎瘤的敏感性和持异性分别为57.9％和99.7％,超声下可见卵巢囊肿共123个,其鉴别囊性畸胎瘤与其他卵巢肿瘤的敏感性和持异性分别为84.6％和
Objective: To evaluate the role of transvaginal ultrasonography in the screening of cystic teratomas and the identification of cystic teratomas and other ovarian tumors. Methods: Transvaginal ultrasonography was performed in 376 nonpregnant non-pregnant women one week prior to laparotomy or laparotomy. The limited or diffuse hyperechoic image as a cystic teratoma ultrasound manifestations. At the same time ultrasound diagnosis and surgery and pathology were compared. Results: A total of 659 ovaries were found under ultrasound. The sensitivity and specificity of screening for cystic teratoma were 57.9% and 99.7% respectively. A total of 123 ovarian cysts were seen under ultrasound, which differentiated cystic teratoma from other The sensitivity and specificity of ovarian tumors were 84.6% and
