Abstract
The value of chest roentgenograms is subject to physical limitations of radiography, temporal limitations of the pathologic processes, and physiologic limitations of the observer. Routine radiologic examination of the chest, special positioning and projections, contrast materials as aids in delineating disease, and specialized technics are described. Image intensification should be used for chest fluoroscopy when possible, especially in infants and children. Survey photofluorography of hospital and clinic patients is still a valuable procedure.
