Diagnostic value of energy spectrum CT combined with chest plain scan in pathological classification of lung cancer
Objective:To investigate the diagnostic value of energy spectrum CT combined with chest plain scan in the pathological classification of lung cancer.Methods:The clinical data of 86 patients with lung cancer admitted to the hospital from January 2021 to March 2022 were retrospectively collected.All patients underwent chest plain scan and energy spectrum enhanced CT scan.The diagnostic value of chest plain scan and energy spectrum enhanced CT scan alone or combined in the diagnosis of lung cancer pathological classification was compared with the results of puncture biopsy as the gold standard.Results:The biopsy results of 86 lung cancer patients showed that 41 cases of lung adenocarcinoma,accounting for 47.67%(41/86),25 cases of lung squamous cell carcinoma,accounting for 29.07%(25/86),and 20 cases of small cell lung cancer,accounting for 23.26%(20/86).Chest plain scan,energy spectrum enhanced CT scan and their combined diagnosis had higher diagnostic accuracy in the diagnosis of lung cancer pathological classification,and the combined diagnosis accuracy was higher,the difference was statistically significant(P<0.05).The results of chest scan and puncture biopsy were in good agreement(0.4<Kappa<0.75).The results of energy spectrum CT enhanced scan,chest plain scan combined with energy spectrum CT enhanced scan and puncture biopsy showed excellent consistency(Kappa>0.75).Conclusion:Both energy spectrum CT and chest plain scan have higher diagnostic value in the pathological classification of lung cancer,and the combined diagnosis value is higher.
