<sup>18</sup>F-FDG pet in the differential diagnosis of lung CANCER
A retrospective analysis of data from PET 18F-FDG in 615 patients with various lung diseases was performed using threshold SUV≥2,5. The sensitivity of PET was 91,8%, specificity is not exceeded 52,2%, diagnostic accuracy — 79,5%, PPV — 80,9%, NPV — 74,2% (p<0,001). New methodological approaches to semiquantitative analysis of PET data are proposed to increase it diagnostic accuracy in the diagnosis of lung cancer.
