Methods: from January 2020 to November 2021, 40 patients of suspected early lung cancer, all received 64 spiral CT scan and pathological examination, referring to the diagnostic value of 64 layers of spiral CT, and the characteristics of 64 spiral CT imaging and CT of early lung cancer cases with CT perfusion parameters. Results: the pathological examination results of 40 patients suspected early lung cancer were 30 malignant, 10 benign, 64 spiral CT showed malignant, 11 benign, 64 layers of spiral CT was 97.50%, 96.67%, specificity was 100.00%;64 spiral CT confirmed malignant cases, deep segmentation, fine spur, spike, the detection rate of vascular tract collection and vacuolar signs was higher than that in benign cases. Blood flow, permeability, blood volume, and mean passage time CT perfusion parameters were higher than benign cases, and the difference was all statistically significant (P <0.05). Conclusion: the 64-layer spiral CT imaging features, fine burr features and spike features are common in the initial diagnosis of early lung cancer patients, and the blood flow, permeability and blood volume are at high levels, which can provide a practical basis for the differentiation between disease diagnosis and benign and malignant.展开更多
