Abstract：Objective To analyze the application value of 64-slice spiral computed tomography(CT)in the diagnosis of mediastinal lung cancer.Methods A total of 50 suspected patients with mediastinal lung cancer treated in our hospital from February 2016 to February 2017 were selected.All patients were performed with 64-slice spiral CT examinations.The postoperative pathological outcomes were used as the gold standard for diagnosis.The diagnostic sensitivity,specificity,and accuracy of 64-slice spiral CT were analyzed.The detection rate of 64-slice spiral CT for different types of lung cancer was also analyzed.Results The diagnostic sensitivity,specificity and accuracy of the 64-slice spiral CT examinations were relatively high,and there was no statistical difference compared with postoperative pathological findings(P＞0.05).The detection rates of different types by 64-slice spiral CT examinations were not displayed statistical significance compared with those in postoperative pathological findings(P＞0.05).Conclusion The application of 64-slice spiral CT in the diagnosis of mediastinal lung cancer is of great value.It has high diagnostic sensitivity,specificity and accuracy,and can accurately distinguish the status of mediastinal lung cancer.
