摘　　要：目的探讨肺孤立性小结节的多层螺旋计算机断层扫描(MSCT)影像学特征及其临床鉴别价值。方法选择2022年2月至2022年9月江西省德兴市中医院收治的90例孤立性肺结节患者作为研究对象,所有患者均接受MSCT检查,观察患者MSCT征象特点,分析MSCT对孤立性肺结节的诊断结果。结果良性结节长径为(1.52±0.27)cm,短于恶性结节的(2.33±0.49)cm,差异有统计学意义(P<0.05);良性结节内部毛刺征、内部分叶征、边缘模糊检出率分别为19%、18%、15%,均低于恶性结节的88%、82%、88%,差异有统计学意义(P<0.05);良性结节实性结节检出率56%高于恶性结节的24%,部分实性结节检出率11%低于恶性结节的35%,差异有统计学意义(P<0.05);良性结节卫星灶、血管集束征象、胸膜凹陷征象检出率分别为5%、16%、15%,均低于恶性结节的24%、65%、76%,差异有统计学意义(P<0.05);良恶性的诊断准确率、特异度、敏感度分别为89%、93%、67%,均表现良好。结论MSCT对肺孤立性小结节具有重要的鉴别价值,可为临床治疗和患者预后提供重要信息。Objective To explore the imaging features and differential clinical value of multi-slice spiral computed tomography(multisliecs helieal CT,MSCT)of solitary small pulmonary nodules.Methods Ninety patients with solitary pulmonary nodules admitted to Dexing Traditional Chinese Medicine Hospital in Jiangxi Province from February 2022 to September 2022 were selected as the study subjects.All patients underwent MSCT examination,and the characteristics of MSCT signs were observed to analyze the diagnostic results of MSCT on isolated pulmonary nodules.Results The average diameter of benign nodules was(1.52±0.27)cm,which was shorter than that of malignant nodules(2.33±0.49)cm,with a statistically significant difference(P<0.05).The detection rates of internal spicule sign,internal lobulation sign,and edge blurring in benign nodules were 19%,18%,and 15%,respectively,which were lower than that of malignant nodules of 88%,82%,and 88%,with statistically significant differences(P<0.05).The detection rate of solid nodules in benign nodules was 56%higher than that in malignant nodules(24%),while the detection rate of some solid nodules was 11%lower than that of malignant nodules(35%),with a statistically significant difference(P<0.05).The detection rates of satellite lesions,vascular cluster signs,and pleural indentation signs in benign nodules were 5%,16%,and 15%,respectively,which were lower than those in malignant nodules(24%,65%,and 76%,respectively),with statistically significant differences(P<0.05).The diagnostic accuracy,specificity,and sensitivity of benign and malignant tumors were 89%,93%,and 67%,respectively,which were all well performed.Conclusion MSCT has important clinical value in distinguishing solitary small pulmonary nodules,and provides important information for clinical treatment and patient prognosis.
