Abstract
In a chest x-ray survey of 10,598 University students carried out during 1947–1948,
3.3 per cent were found to have abnormalities requiring clinical investigation. Approximately
one-half of these abnormalities, however, were found not to exist on 14 in. by 17
in. films. The abnormalities of the remaining half consisted of:
- 1.(a) Pulmonary infiltrates: 14 per cent of which were found to be active tuberculous lesions; 30 per cent of which, though the etiology was not demonstrated, were found to be nontuberculous on the basis of insensitivity of the patient to tuberculin; the remaining 56 per cent, etiology not demonstrated, could potentially be found in later examinations to be tuberculous on the basis of sensitivity of the patient to tuberculin.One-half of the persons with infiltrates had no knowledge of the existence of their disease. The detection of the lesions in this group alone amply reaffirms the value of routine x-raying of the chest.
- 2.(b) Skeletal abnormalities: the finding of previously undetected abnormalities of potential harm was limited to two patients with supernumerary ribs and one with a rib cyst.
- 3.(c) Cardiac abnormalities: previously undetected abnormalities consisted of congenital defects and cardiac enlargement of unknown cause.
- 4.(d) Miscellaneous abnormalities: previously undetected abnormalities consisted of a hilar mass and a cardiophrenic mass, neither of which has been identified.
A chest x-ray provides a means of detecting a wide variety of unsuspected chest abnormalities
and should be included routinely in every general medical examination.
