Modern perspective diagnosis programs for studying the possibilities of bronchogenic cancer screening are based on virtual spiral NLS using. In comparison with rontgenography and fluorography the main advantage of this technology is fundamentally high resolution. Using virtual NLS allows effective exposure of nidi in lung tissue sizing 0.5-0.7 mm. In most of major researches it is shown that virtual NLS of metatron hunter 4025 allows revealing lung nidi of 10-12% patients from high-risk group, where 0.5 - 1.5% are bronchogenic cancer. More than 80% of these tumors are not seen while rontgenography, resolution limit of which is 3-5mm. NLS can expose cancer at first stage of 80-95% of patients.

    The main limitations for virtual NLS-scopy of bronchogenic cancer screening wide application are high number of false-positive results, the lack of conclusive proofs in decreasing of patients death rate in screening groups compared with other groups or population as a whole.
