Objective and Methods: The hypothesis that early detection of lung cancer by means of mass screenings should reduce the mortality from the disease eluted the idea to include chest CT examinations in mass screening for lung cancer. The recent development of mobile CT installed in busses has made this feasible. The mobile CT, however, has some mechanical limitations in order to. fit in the small space available. To evaluate the equipment, mobile, conventional, and high resolution CT (HRCT) images of 13 peripherally located small pulmonary lesions, including six neoplastic lesions, were compared. Results: The results showed that the mobile CT was equivalent to the conventional CT and satisfactory for detecting even very small pulmonary lesions. The mobile and conventional CT, however, are not always sufficient enough to scrutinize detailed structures of the lesions when compared to the HRCT. Conclusion: The mobile CT is sufficient for mass screening for lung cancer, if followed by HRCT for detected lesions.
