Abstract：Objective To investigate the characteristics of DR and low dose spiral (LDCT) imaging and to provide diagnosis for early lung cancer .Methods 53 patients with pathologically confirmation on the early stage of lung cancer were retrospectively analyzed .A comparison of the imaging manifestations of DR and LDCT in early lung cancer was performed .Results Central type of lung cancer DR showed hilar enlargement thickening and nodular density increased shadow .Early peripheral lung cancer showed circular , elliptic increased density shadow , with edge burr and lobulated features .Obstructive lung changes and pulmonary nodules were characterized by LDCT central type of lung cancer with 81%in lobulation, 65%in burr, 53%in a pleural sag, 38%in blood vessels of cluster and 16%in GGO.Of 53 cases of patients , DR positive rate was 33%and LDCT positive rate was 90%(χ2 =8.63 , P<0.01 ) .Conclusion LDCT is better than DR for diagnosis of early lung cancer with obviously signs and higher posi -tive detection rate .
