[en] The diagnostic value of the tomogram of digital radiography (CR tomogram) was evaluated in comparison with that of the xerotomogram in 33 patients with small peripheral-type lung lesions, including 22 who were operated on. The margin of the lesions, pleural retraction, involved bronchi, involved vessels, cavity formations and other abnormalities were as clearly visualized by CR tomography as by xerotomography. The thickness of the third or fourth order bronchi could also be observed on the CR tomogram. The CR tomogram proved to be of as much value as the xerotomogram for the diagnostic delineation of the features of peripheral-type lung lesions. (author)
