【Abstract】 ObjectiveTo investigate the diagnostic value of multi-slice spiral CT （MSCT） signs in patients with solitary pulmonary nodules （SPN）on the pathological properties.MethodsAretrospective study was conducted to collcttheclinical dataof 107 patientswith SPNadmitedtothehospital fromFebruary 2022 toFebruary 2024. All patients were divided into a benign group of 44 cases （41.1%） and a malignant group of 63 cases （58.9% based on pathological examinationresults.Allpatients underwent MSCTexaminationbefore treatment，andthe MSCT signs of thetwo groups werecompared.Binary Logistic regresion was used to analyze the relationship between MSCT signsand pathological properties of SPN in SPN patients.Thereceiver operatingcharacteristic （ROC）curves were drawn to analyze the diagnostic value of MSCT signs for benign and malignant SPN.ResultsThe proportion of malignantpatientswith lobulationsigns，short hairprick signs，pleural depression signs，vascularbundlesigns，and vacuolar signs was higher than that of the benign group，the proportion of calcified patients in the malignant group was lower than thatin the benign group，andthe diameter of nodules in the malignant group was largerthan that in the benign group （ P <0.05）.Binary Logistic regression analysis showed that lobulation sign，short burr sign，pleural indentationsign，vascular convergence sign，and nodule diameter were risk factors for malignant SPN（OR>1， P< 0.05），and calcification was a protective factor for malignant SPN（OR <1 ，P<0.05）. The ROC curve results showed thatthe areaunder the curve （AUC）（95%CI）of MSCT signs combinedwith thepathological nature of SPN in patients with SPN was O.912（0.860，0.963，P

孤立性肺结节（solitarypulmonarynodule，SPN）是一种常见的肺部病变，多为隐匿性起病，结节相对较小，该疾病早期缺乏临床表现，多数患者无明显症状，少数患者偶有刺激性咳嗽、咳痰、痰血、胸痛[1]。（剩余5875字）
