Observation of Multi-slice Spiral CT in TNM Staging Diagnosis of Peripheral Lung Cancer
Objective:To study the clinical value of multi-slice spiral CT(MSCT)in diagnosing TNM staging of pe-ripheral lung cancer.Methods:200 patients with peripheral lung cancer admitted to hejian city People's Hospital from May 2022 to May 2024 were selected,and MSCT and X-ray examinations were performed on all patients.The results of surgical and pathological diagnosis were taken as the gold standard,and the value of MSCT in diagno-sing TNM staging of peripheral lung cancer was analyzed.Results:The positive detection rate of MSCT in diagno-sing pulmonary lesions was 93.00%(186/200),and that of extrapulmonary lesions was 59.00%(118/200),both higher than that of X-ray diagnosis,P<0.05.According to the TNMgrading system of surgical pathology,the ac-curacy of MSCT in clinical grading diagnosis of peripheral lung cancer is 91.00%,while the accuracy of X-ray in clinical grading diagnosis of peripheral lung cancer is only 62.00%.The accuracy of MSCT in diagnosing TNM staging of peripheral lung cancer was significantly higher than that of X-ray,P<0.05.The time and cost of X-ray examination were lower in CT than in MSCT,P<0.05.Conclusion:MSCT is of high clinical value in TNM staging diagnosis of peripheral lung cancer.
