Discrepancies are frequently noted between the degree of lung involvement as shown by the roentgenogram and the severity of subjective symptoms of the patient. With the advent of pulmonary functional studies, such as bronchospirometry and pulmonary artery catheterization, discrepancies were still observed between the degree of functional impairment and the degree of involvement on the roentgen-ray picture. It is also well known that there is often very little correlation between cardiorespiratory insufficiency that is observed in silicotics and the degree of pulmonary involvement as seen both on roentgenographic picture and at postmortem examination.
