目的:比较超声造影(CEUS)和增强CT(CECT)鉴别诊断肾实质性恶性肿瘤的临床价值。方法:将93例肾脏肿瘤患者分别给予CEUS与CECT检查,将诊断结果与病理检查结果作对照,比较两种诊断方法的敏感度、特异度和准确率。结果:两种诊断方法的特异度无显著差异,P>0.05;而CEUS对肾脏恶性肿瘤诊断的敏感度及准确率均显著优于CECT,P<0.05。结论:CEUS在鉴别诊断肾实质性肿瘤方面较CECT在敏感度和准确率上具有一定的优势,临床上二者联合应用可优势互补,提高肾脏肿瘤的鉴别诊断价值。
Objective: To compare the clinical value of contrast-enhanced ultrasonography (CEUS) and enhanced CT (CECT) in differentiating renal parenchymal malignancies. Methods: Ninety-three patients with renal tumors were treated with CEUS and CECT respectively. The diagnostic results were compared with the pathological findings. The sensitivity, specificity and accuracy of the two diagnostic methods were compared. Results: The specificity of the two diagnostic methods was no significant difference (P> 0.05). The sensitivity and accuracy of CEUS in the diagnosis of renal malignancy were significantly better than that of CECT (P <0.05). Conclusion: CEUS has some advantages over CECT in sensitivity and accuracy in the differential diagnosis of renal parenchymal tumors. Clinically, CEUS can complement each other and improve the differential diagnosis of renal tumors.
