[Problems in radiology of concealed lung disorders (author's transl)]

The problems of diagnostic radiology in dealing with discreet and difficult to find pathological lung conditions are demonstrated by typical examples. Special emphasis is given to localized changes found in paramediastinal and paracardial regions of the lung and the diaphragm. Special attention was given to patients with elusive or hidden lung disorders and the value of information by X-rays of more than one dimension, by spot films taken during fluoroscopy, by bronchography, by tomography, and by computed tomography is discussed. Early diagnosis of lung and bronchial carcinoma as well as infections of the lung parenchyma can only be found, if the radiological methods are optimally used.
