摘要
目的比较多层螺旋CT增强扫描与MRI对肾实性肿瘤鉴别诊断的效果差异。方法以自2017年12月—2020年12月于宁海县第一医院就诊的140例肾脏肿瘤患者为研究对象,全部病例均进行多层螺旋CT增强扫描检测和MRI检测,以组织病理检测结果为金标准,统计分析2种检测手段对不同病理类型和不同病灶大小肾脏肿瘤性质鉴别诊断的诊断效能差异。结果多层螺旋CT增强扫描检测对不同病例类型肾实性肿瘤定性诊断灵敏度、特异度和准确率(88.68%、85.29%和87.86%)与MRI检测水平(90.57%、82.35%和88.57%)差异均无统计学意义(χ^(2)=0.203、0.108、0.034;P=0.652、0.742、0.853);多层螺旋CT增强扫描检测对直径≥4 cm的肾实性肿瘤定性诊断灵敏度、特异度和准确率(95.45%、92.31%和94.74%)与MRI检测水平(97.73%、92.31%和96.49%)差异均无统计学意义(χ^(2)=0.345、0.000、0.209;P=0.557、0.999、0.647);多层螺旋CT增强扫描检测与MRI检测对直径<4 cm的肾实性肿瘤定性诊断灵敏度、特异度和准确率(83.87%、80.95%和83.13%)与MRI检测水平(85.48%、76.19%和83.13%)差异均无统计学意义(χ^(2)=0.345、0.141、0.999;P=0.557、0.707、0.999)。结论多层螺旋CT增强扫描检测与MRI检测对肾实性肿瘤均具有较高临床应用价值,且对于小体积肾实性肿瘤均具有较高鉴别诊断效能,临床可根据患者实际情况合理选择诊断方式。
Objective To compare the effect of multi-slice spiral CT enhanced scan and MRI in the differential diagnosis of renal parenchymal tumours.Methods A total of 140 patients with renal tumours in our hospital from December 2017 to December 2020 were selected as the research objects.All cases were examined by multi-slice spiral CT enhanced scan and MRI.The results of histopathological examination were taken as the gold standard,and the diagnostic efficiency of the two methods in the differential diagnosis of different pathological types and different lesion sizes of renal tumours were statistically analysed.Results No significant difference was observed in the sensitivity,specificity and accuracy of multi-slice spiral CT enhanced scan(88.68%,85.29%and 87.86%)and MRI(90.57%,82.35%and 88.57%)(χ^(2)=0.203,0.108,0.034;P=0.652,0.742,0.853).Moreover,no significant difference was observed in the sensitivity,specificity and accuracy of multi-slice spiral CT enhanced scan(95.45%,92.31%and 94.74%)and MRI(97.73%,92.31%and 96.49%)in the qualitative diagnosis of renal parenchymal tumour with diameter>4 cm(χ^(2)=0.345,0.000,0.209;P=0.557,0.999,0.647).The sensitivity,specificity and accuracy of multi-slice spiral CT enhanced scan and MRI in the qualitative diagnosis of renal parenchymal tumour with diameter<4 cm(83.87%,80.95%and 83.13%)were not significantly different from those of MRI(85.48%,76.19%and 83.13%,χ^(2)=0.345,0.141,0.000;P=0.557,0.707,0.999).Conclusion Multi-slice spiral CT enhanced scan detection and MRI detection have high clinical application value for the diagnosis of renal parenchymal tumours,and have high differential diagnosis efficiency for small renal parenchymal tumours.Clinical diagnosis can be reasonably selected according to the actual situation of patients.
