摘要
目的分析MRI检查对鉴别孤立性肺结节(Solitary pulmonary nodule,SPN)病变性质的临床价值。方法回顾性分析本院2019年8月至2020年6月收治且经胸外科手术或病理诊断确诊的108例SPN患者的临床资料。以病理诊断为“金标准”,分析MRI诊断SPN的敏感性、特异性及准确性,并比较不同b值中良、恶性SPN的ADC值。结果108例SPN患者中恶性结节64例,良性结节44例;在b值=200s/mm^(2)、1000s/mm^(2)情况下,良、恶性SPN的ADC值比较无明显差异(P>0.05);b值=500s/mm^(2)、800s/mm^(2)情况下,良性SPN的ADC值显著高于恶性SPN(P<0.05),且b值=500s/mm^(2)时,MRI检查鉴别诊断良、恶性SPN的敏感性、特异性及准确性更高,分别为85.94%、75.00%、81.48%,漏诊、误诊率分为14.06%、25.00%。结论MRI检查在诊断效良、恶性SPN中具有一定的价值,能有效显示其形态学特征,具有较高的灵敏度、特异度,能为临床治疗提供可靠的依据。
Objective To analyze the clinical value of MRI examination in identifying the nature of lesions of solitary pulmonary nodule(SPN).Methods The clinical data of 108 SPN patients admitted to our hospital from August 2019 to June 2020 and confirmed by thoracic surgery or pathological diagnosis were retrospectively analyzed.The pathological diagnosis was regarded as the"gold standard".The sensitivity,specificity and accuracy of MRI in the diagnosis of SPN were analyzed,and the ADC values of benign and malignant SPN in different b values were compared.Results Among 108 SPN patients,64 cases were malignant nodules and 44 cases were benign nodules.In the case of b value=300s/mm^(2),800s/mm^(2),there is no significant difference between the benign and malignant SPN in the ADC value(P>0.05).In the case of b value=500s/mm^(2),the ADC value of benign SPN is significantly higher than that of malignant SPN(P<0.05).And the sensitivity of MRI in the differential diagnosis of benign and malignant SPN is 85.94%,the specificity is 75.00%,the accuracy is 81.48%,and the rate of missed diagnosis and misdiagnosis is 14.06%and 25.00%,respectively.Conclusion MRI examination has some value in the diagnosis of benign and malignant SPN,can effectively display its morphological characteristics,has high sensitivity and specificity,and can provide a reliable basis for clinical treatment.
