DWI与CT在肾脏占位性病变术前诊断中的应用价值分析

目的对比分析磁共振扩散加权成像(DWI)与电子计算机断层扫描(CT)在肾脏占位性病变术前诊断中的应用价值。方法选择2016年1月到2019年1月到我院就诊的肾脏占位病变患者98例,其中以肾脏良性病变患者38例为良性组,肾脏恶性病变患者60例为恶性组;所有患者均进行DWI及CT检测。统计两种检测方式的诊断效能、对良恶性病灶的检出率,以及对不同类型疾病诊断符合率。结果 DWI检测诊断准确性高于CT检测,差异具有统计学意义(P<0.05);两种检测方式诊断灵敏性及特异性无统计学差异(P>0.05);两种检测方式对良恶性病灶的检出率差异无统计学意义(P>0.05);DWI对不同类型疾病诊断总符合率高于CT(P>0.05)。结论 DWI检测肾脏占位病变准确率高于CT检测。

Analysis of Application Value of DWI and CT in the Preoperative Diagnosis of Renal Space-occupying Lesions

Objective To analyze the application value of diffusion-weighted imaging(DWI) and computed tomography(CT) in the preoperative diagnosis of renal space-occupying lesions.Methods 98 patients with renal space-occupying lesions treated in the hospital from January 2016 to January 2019 were selected.38 patients with benign renal space-occupying lesions were sassigned as benign group,and60 patients with malignant renal space-occupying lesions were set as malignant group.All patients were tested by DWI and CT.The diagnostic efficacy of the two detection methods was counted,and the detection rates of benign and malignant lesions by the two detection methods were calculated,and the diagnostic coincidence rate of the two detection methods for different types of diseases was counted.Results The diagnostic accuracy of DWI was higher than that of CT(P<0.05).There were no statistically significa nt differences in the sensitivity and specificity between the two methods(P>0.05),There was no significant difference in the detection rate of benign and malignant lesions by the two methods(P>0.05).The total coincidence rate of DWI was higher than that of CT in diagnosing different types of diseases(P<0.05).Conclusion The accuracy rate of DWI is higher than that of CT in detecting renal space-occupying lesions.
