超声造影与多层螺旋CT增强扫描在肾肿瘤诊断中的对照研究

目的比较超声造影与多层螺旋CT增强扫描对肾肿瘤的诊断价值。方法回顾性分析55例经手术病理证实的且有完整临床资料的肾肿瘤的超声造影及多层螺旋CT增强扫描表现特点,并以手术病理结果为参考标准,评价超声造影与多层螺旋CT增强扫描诊断肾肿瘤的价值。结果 55例病灶中,34例为恶性病变,21例为良性病变;超声造影诊断肾肿瘤的敏感性、特异性、阳性预测值、阴性预测值分别为90.6%、78.3%、85.3%、85.7%;多层螺旋CT增强扫描诊断肾肿瘤的敏感性、特异性、阳性预测值、阴性预测值分别为87.5%、73.9%、82.3%、81.0%;两种检查方法检查结果差异无统计学意义(P0.05)。结论超声造影与多层螺旋CT增强扫描对于肾肿瘤的诊断效果相当,临床可以根据检查技术的特点,为不同的患者选择适宜的检查。

Controlled studies of contrast-enhanced ultrasound and contrast-enhanced CT in the diagnosis of renal tumor

Objective To compared the value of contrast-enhanced ultrasound(CEUS)with contrast-en-hanced CT(CECT)in the diagnosis of renal tumor.Methods The CEUS and CECT features of 55 cases of renal tumor confirmed by operation and pathology were retrospectively analyzed,evaluate the value of CEUS and CECT in the diagnosis of renal tumor.Results Of the 55 cases,21 cases showed benign lesions,and 34 cases malignant lesions.The sensitivity,specificity,positive predictive value,and negative predictive value of the CEUS were 90. 6%,78.3%,85.3%,and 85.7%,respectively;and the sensitivity,specificity,positive predictive value,and negative predictive value of the CECT were 87.5%,73.9%,82.3%,81.0%.There was no significant difference in the results between two methods(P >0.05).Conclusion CEUS can get the same effect as the CECT.The suit-able method is selected according to the characteristics of the inspection technology.
