超声造影对盆腔肿块定性诊断的初步研究

Characterization of complex pelvic masses with contrast-enhanced ultrasound

目的探讨超声造影对盆腔肿块的定性诊断价值。方法对137例盆腔肿块患者进行超声造影检查，依据肿瘤的影像增强特征作出定性诊断，结果与病理对照，应用诊断性试验对超声造影的定性诊断效能进行评估。结果超声造影定性诊断恶性病灶的敏感性、特异性、阳性预测值、阴性预测值、准确性及ROC曲线下面积分别为85．3％（29／34）、93．2％（96／103）、80．6％（29／36）、95．0％（99／101）、91．2％（125／137）、0．892。结论超声造影为临床定性诊断盆腔肿块提供了一种简单准确的新方法。

Objective To assess the diagnostic performance of contrast-enhanced ultrasound in characterization of pelvic masses. Methods Contrast-enhanced ultrasound was performed on 137 patients with pelvic masses. The results were compared to pathological diagnostic criteria. The diagnostic performance was evaluated by using diagnostic test. Results Sensitivity, specificity, positive predictive value, negative predictive value, accuracy and area under ROC curve in diagnosing complex pelvic masses by using contrast-enhanced ultrasound were as follows： 85.3% （29/34）, 93.2% （96/103）, 80.6% （29/36）, 95.0% （ 99/101 ）, 91.2% （ 125/137 ）, 0. 892, respectively. Conclusions Contrast-enhanced ultrasound provides a simple and curate method for characterization of pelvic masses.
