【摘要】：目的比较超声造影、增强CT及增强MRI对肾脏占位性病变的诊断价值。资料与方法对78例经常规超声诊断为肾脏占位性病变患者的80个病灶进行实时超声造影检查,39个行增强CT检查,28个行增强MRI检查,其中5个同时行增强CT及增强MRI检查。以病理结果为"金标准",比较超声造影、增强CT及增强MRI诊断肾脏占位性病变良恶性的价值。结果 80个病灶中,57个为恶性病变,23个为良性病变;超声造影诊断肾脏病变良恶性的敏感度、特异度、阳性预测值、阴性预测值分别为93.0%、69.6%、88.3%、80.0%;增强CT诊断肾脏病变良恶性的敏感度、特异度、阳性预测值、阴性预测值分别为96.4%、72.7%、90.0%、88.9%;增强MRI诊断肾脏病变良恶性的敏感度、特异度、阳性预测值、阴性预测值分别为86.4%、66.7%、90.5%、57.1%;3种检查诊断效果间差异无统计学意义(P0.05)。结论超声造影、增强CT及增强MRI对于肾脏占位性病变良恶性的诊断效果相当,临床可以根据各个检查技术的特点,为不同的患者选择适宜的检查,联合应用两种检查方法为肾脏占位性病变的诊断提供了更丰富的信息。
[Abstract]:Objective to compare the diagnostic value of contrast-enhanced CT and enhanced MRI in renal space-occupying lesions. Materials and methods Real-time contrast-enhanced CT was performed on 80 lesions in 78 patients with renal space-occupying lesions diagnosed by conventional ultrasound. Enhanced CT was performed in 39 patients and enhanced MRI was performed in 28 patients. Among them, 5 lesions were examined with enhanced CT and enhanced MRI simultaneously. The value of contrast-enhanced CT and enhanced MRI in the diagnosis of benign and malignant renal space-occupying lesions was compared. Results of the 80 lesions, 57 were malignant lesions and 23 were benign lesions. The sensitivity, specificity, positive predictive value and negative predictive value of contrast-enhanced ultrasonography in the diagnosis of benign and malignant renal lesions were 93.0 and 80.0, respectively. The sensitivity, specificity, positive predictive value and negative predictive value of CT in the diagnosis of benign and malignant renal lesions were 96.4 and 90.088. 9 respectively. The sensitivity, specificity, positive predictive value and negative predictive value of MRI in the diagnosis of benign and malignant renal lesions were 86.4 and 90.5%, respectively. There was no significant difference in diagnostic effect among the three examinations (P0.05). Conclusion contrast-enhanced ultrasonography, enhanced CT and enhanced MRI are comparable in the diagnosis of benign and malignant renal space-occupying lesions. According to the characteristics of various examination techniques, appropriate examinations can be selected for different patients. Combined use of two methods provides more information for the diagnosis of renal space-occupying lesions.
