title: [A comparison of xero-tomography of the lung hilum with conventional tomography (author's transl)].
abstract: Because of its particular photoelectric properties, xero-tomography is particularly suited for the investigation of abnormalities in the hilar regions. It is superior to conventional tomography because of the improved edge contrast, which emphasises details of relatively non-opaque structures, and because of its high exposure latitude. This justifies its use despite the higher radiation dose that is necessary. The demonstration of relatively dense and of more transradient tissues on the same picture by xero-tomography, and the ability to read it by ordinary light, makes it less tiring to interpret than the translucencies of conventional radiographs.
