摘　　要：目的:探讨SPLC与PIN的MSCT征象对比及其鉴别诊断价值。方法:选取74例于2019年4月至2023年7月收治的SPLC患者为SPLC组,同期46例PIN患者为PIN组,分析MSCT对SPLC与PIN的鉴别诊断价值,并比较SPLC与PIN的征象差异以及影像学特点。结果:病理学检查结果显示有6例SPLC患者被误诊为PIN,8例PIN患者被误诊为SPLC,总误诊率为14例,准确度为88.33%(106/120)。在5mm和1mm重建征象中,SPLC患者在分叶征、毛刺征、胸膜凹陷征、血管集束征等多种征象的占比均高于PIN患者(P<0.001)。SPLC患者动脉期CT增加值亦高于PIN患者(P<0.001)。结论:MSCT能有效鉴别SPLC与PIN,为SPLC与PIN的诊疗提供参考。Objective:Exploring the comparison and differential diagnostic value of MSCT features between peripheral SPLC and PIN.Method:74 SPLC patients admitted from April 2019 to July 2023 were selected as the SPLC group,while 46 PIN patients were selected as the PIN group during the same period.The differential diagnostic value of MSCT for SPLC and PIN was analyzed,and the differences in signs and imaging characteristics between SPLC and PIN were compared.Result:Pathological examination showed that 6 SPLC patients were misdiagnosed as PIN,and 8 PIN patients were misdiagnosed as SPLC.The total misdiagnosis rate was 14 cases,with an accuracy of 88.33%(106/120).In the reconstruction signs of 5mm and 1mm,the proportion of SPLC patients in various signs such as lobulation sign,hairpin sign,pleural depression sign,and vascular bundle sign was higher than that of PIN patients(P<0.001).The arterial CT increase in SPLC patients was also higher than that in PIN patients(P<0.001).Conclusion:MSCT can effectively distinguish between SPLC and PIN,providing reference for the diagnosis and treatment of SPLC and PIN.
