Abstract: Objective To evaluate the prevalence rate of pulmonary malignant disease in people at high risk of lung cancer through low-dose multi-slice spiral CT. Methods 1 200 symptom-free volunteers were under low-dose spiral CT scans in an on-going screening study. The people tested aged 40 or older regardless of their gender or smoking history. Low-dose CT scans were performed with Iightspeed Plus multi-slice scanner using spiral mode, 120 kV,30 mAs. Results Calcified nodules were detected in 32 participants and non-calcified nodules were detected in 18 participants by low-dose CT,in which 3 were vicious ones,including 1 non-solid lesion and 2 solid lesions. The detection rate of lung cancer was 0. 25%. Conclusion Low-dose multi-slice spiral CT was effective in detecting, classifying and defining lung nodules,and furthermore would make it possible to find lung cancer at earlier stage.
