Comparison and differential diagnostic value of MSCT signs between peripheral small lung cancer and pulmonary nodules
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.
