摘要
目的比较常规超声和超声造影对良恶性肾囊性肿物的诊断效能。方法对29例患者(29个肾囊性肿物)行常规超声和超声造影检查,并进行良恶性分类,与病理结果进行比较,计算其敏感性、特异性、准确性、阳性预测值、阴性预测值及曲线下面积,分析两种检测方法的一致性,比较二者对肾恶性囊性肿物的诊断效能。结果常规超声和超声造影诊断肾恶性囊性肿物的敏感性、特异性、准确率、阳性预测值、阴性预测值及曲线下面积分别为66.7%vs.94.4%、72.7%vs.81.8%、68.9%vs.89.7%、80.0%vs.89.5%、57.1%vs.90.0%及0.697 vs.0.874,超声造影与常规超声诊断肾脏恶性囊性肿物准确率比较差异有统计学意义(P=0.04)。结论超声造影对肾恶性囊性肿物具有较高的诊断效能。
Objective To compare the diagnostic efficacy of conventional ultrasound（US） and contrast-enhanced ultrasound（CEUS）in renal cystic lesions.Methods Twenty-nine patients with twenty-nine renal cystic lesions underwent CEUS and US.All masses were graded benign or malignant according to features of the US and CEUS images,and the terminal diagnosis of these lesions were confirmed by pathology.The sensitivity,specificity,accuracy,positive predictive value,negative predictive value and the diagnostic consistency were evaluated,then the diagnostic value of US and CEUS were compared.Results The sensitivity,specificity,accuracy,positive predictive value,negative predictive value and the area under the ROC curves of US and CEUS were 66.7% vs. 94.4%,72.7% vs. 81.8%,68.9% vs. 89.7%,80.0% vs. 89.5%,57.1% vs. 90.0%,0.697 vs. 0.874,respectively.There were significant differences in diagnosing renal malignant cystic lesions between two methods（P =0.04）.Conclusion CEUS is helpful for improving the diagnostic efficacy of renal malignant cystic mass.
