摘　　要：目的研究多层螺旋CT图像后处理技术在肺部结节鉴别诊断中的应用价值。方法选择2020年5月-2021年5月我院肺部结节行多层螺旋CT(MSCT)检查的患者78例,将CT扫描原始图像定义为对照组,将后处理图像定义为观察组,病理诊断为金标准,比较两组结节征象显示率、良恶性结节诊断率以及诊断效能。结果观察组后处理图像分叶、毛刺、血管集束、胸膜凹陷、支气管截断、空泡各征象显示率均高于对照组,差异有统计学意义(P<0.05);观察组恶性和良性结节诊断率均高于对照组,差异有统计学意义(P<0.05);观察组诊断敏感度、特异度、阳性预测值、阴性预测值均高于对照组,差异有统计学意义(P<0.05)。结论多层螺旋CT图像后处理技术在肺部结节鉴别诊断中具有重要的价值,可提高诊断准确率、敏感度、特异度,与术后病理诊断结果吻合度较高,可一定程度降低漏诊和误诊,提高肺部结节的诊断,是一种鉴别诊断肺部结节的有效手段。Objective To study the application value of multi-slice spiral CT image post-processing technology in the differential diagnosis of pulmonary nodules.Methods 78 patients with pulmonary nodules who underwent multi-slice spiral CT(MSCT)examination in our hospital from May 2020 to May 2021 were selected.The original image of CT scan was defined as the control group,and the post-processing image was defined as the observation group.The pathological diagnosis was the gold standard.The display rate of nodule signs,the diagnostic rate of benign and malignant nodules and the diagnostic efficiency were compared between the two groups.Results The display rates of lobulation,burr,vascular bundle,pleural indentation,bronchial truncation and vacuoles in the post-processing images of the observation group were higher than those of the control group,and the differences were statistically significant(P<0.05).The diagnostic rate of malignant and benign nodules in the observation group was higher than that in the control group,and the difference was statistically significant(P<0.05).The diagnostic sensitivity,specificity,positive predictive value and negative predictive value of the observation group were higher than those of the control group,and the difference was statistically significant(P<0.05).Conclusion Multi-slice spiral CT image post-processing technology has important value in the differential diagnosis of pulmonary nodules,which can improve the diagnostic accuracy,sensitivity and specificity,and is highly consistent with the postoperative pathological diagnosis results.It can reduce the missed diagnosis and misdiagnosis to a certain extent,and improve the diagnosis of pulmonary nodules,which is an effective means of differential diagnosis of pulmonary nodules.
