Abstract:
Objective To investigate the CT feature of small cell lung cancer(SCLC),and investigate the clinical value.Methods 55 patients with SCLC and 118 patients with non -small cell lung cancer(NSCLC)were selected as the study subjects.All the patients were confirmed by pathology,the CT feature of lung cancer were com-pared through unenhanced and enhanced scanning by philips brilliance 16 spiral CT.Results There were significant differences between the SCLC group and NSCLC group in tumor type and morphology(χ2 =22.628,21.249,all P <0.01).Central was the mainly type of SCLC,irregular shape and round was the mainly type of NSCLC.The positive rates of positive airway occlusion,pulmonary atelectasis or obstructive pneumonia in central SCLC group and NSCLC group were 57.78% and 86.27%,62.22% and 98.04%,which in central SCLC group were lower than NSCLC group (χ2 =9.830,20.131,all P <0.01).The Hilar and mediastinal lymph nodes positive rate,fusion of lymph node -pos-itive rate,combined positive rate of violations of mediastinal vessels in central SCLC group and NSCLC group were 90.9% and 49.15%,58% and 15.52%,54.55% and 7.63%,which in central SCLC group were greater than the NSCLC group(χ2 =27.887,53.070,47.294,all P <0.01).Conclusion 16 -slice spiral CT can provide important information for diagnosis of SCLC and NSCLC,the CT signs are conducive to the diagnosis of NSCLC,which contai-ning round mass,bronchial smooth,hilar and mediastinal lymph nodes,lymph nodes are not fused with obstructive pneumonia and atelectasis,mediastinal vascular invasion.
