摘要
目的探讨经阴道超声造影诊断宫内膜病变的临床应用价值。方法 43例疑为宫内膜病变的患者根据病理结果分为恶性组11例、良性组32例及正常内膜3例,均行经阴道超声造影检查,以子宫正常肌层为参照物,观察两组病灶的增强时相、模式及强度等指标,分析时间-强度曲线,比较两组超声造影的差异。结果恶性组病灶超声造影特点为早增强和高增强,阳性预测值分别为70.0%和66.0%;良性组病灶超声造影特点为晚增强和低、等增强,阳性预测值分别为85.0%和88.8%。两组病灶的灌注时相和增强强度比较,差异均有统计学意义(均P<0.05);而清退时相和增强模式比较差异均无统计学意义;两组内各病理类型超声造影比较差异均无统计学意义。结论经阴道超声造影在鉴别宫内膜良、恶性病变中有重要的临床价值。
Objective To evaluate the clinic value for endometrial disease using transvaginal contrast-enhanced ultrasound. Methods Forty-three cases of endometrial lesions were included in this study,according to pathological results,they were divided into malignant group（n=11） and benign group（n =32）. Normal uterine myometrium was used as contrast. The enhanced phase,pattern,scale of contrast enhanced ultrasound,and the TIC curve analysis were recorded and compared between the malignant and benign groups. Results Compared with the pathology, malignant lesions enhancement occurred earlier and showed fluent enhancement,the positive predictive value were 70.0% and 66.0%,respectively. Similarly, for benign lesions, the enhancement occurred later,the scale of enhancement was relatively lower,the positive predictive value were 85.0% and 88.8%.There was significant difference of phase and scale of enhancement between two groups（all P〈0.05）. However, there were no signifcant difference of washing phase and the enhance mode between two groups. No enhancement mode difference was found among different pathological types.Conclusion Transvaginal contrast-enhanced ultrasound is useful for endometrial lesions identification diagnosis.
