Objective To explore the application value of CT enhanced delayed scanning in preoperative diagnosis of non-small cell lung cancer（NSCLC）．Methods A retrospective analysis was conducted on 82 patients with NSCLC who underwent surgical treatment in a hospital from May 2021 to May 2024．They were included into an observation group and another 82 patients with benign lung tumors were included in the control group．The preoperative CT enhanced delayed scanning results were collected,and the postoperative pathological diagnosis was used as the “gold standard” to analyze the application value of CT enhanced delayed scanning in the preoperative diagnosis of NSCLC．And the CT enhancement values of delayed CT scans in NSCLC patients with different clinical and pathological features were compared,and Spearman correlation analysis was used to analyze the relationship between CT enhancement values and pathological features of NSCLC．Results CT enhanced delayed scanning showed that the number of lobular（12.50% vs 53.57%）and internal vacuolar signs（6.25% vs 39.29%）in the observation group was significantly lower than that in the control group（χ²=26.560,24.680,P<0.05）,while the edge spicules（56.25% vs 17.86%）and chest depression signs（59.38% vs 14.29%）in the observation group were significantly higher than that in the control group（χ²=43.330,64.600,P<0.05）．A total of 79 cases of 82 NSCLC were diagnosed by CT-enhanced delayed scan,and the accuracy of CT-enhanced delayed scan diagnosis for NSCLC was 96.34%（79/82）,with no significant difference from the pathological diagnosis result of 100.00%（χ²=3.060,P=0.080）．The average CT enhancement value of 82 NSCLC cases was（39.14±7.31）．There was no significant difference in CT enhancement values among patients of different genders,ages,maximum tumor diameter,and lymph node infiltration（P>0.05）．Patients with different pathological types [adenocarcinoma（43.75±7.15）vs squamous cell carcinoma（34.74±6.12）],degree of cell differentiation [moderate,and low differentiation（45.7±7.21）vs high differentiation（32.81±5.11）],clinical stage [I（31.03±2.12）vs II（36.61±3.13）vs IIIa（46.32±6.83）] and lymph node metastasis [yes（42.75±4.21）,vs no（35.77±8.13）] CT enhancement had significant difference（t/F=5.243,8.804,84.828,4.378,P<0.05）．The Spearman correlation analysis results showed that pathological type,degree of cell differentiation,clinical stage,lymph node metastasis were positively correlated with CT enhancement values in NSCLC patients（r=0.431,P=0.021;r=0.511,P=0.009;r=0.586,P=0.005;r=0.579,P=0.008）．Conclusions CT enhanced delayed scanning has important value in preoperative diagnosis of NSCLC．Its diagnostic accuracy is not significantly different from pathological diagnosis,and the CT enhanced value of patients can be determined through CT enhanced delayed scanning,providing reference for postoperative pathological feature judgment of NSCLC patients．
