In an effort to determine if routine prenatal chest roentgenograms were of practical value, the records of 12,109 consecutive deliveries at the Mayo Clinic were reviewed retrospectively. The roentgenograms were obtained during the first or second prenatal visit and additionally when warranted by notable symptoms or physical findings in subsequent prenatal visits. Forty-eight patients had appreciable roentgenographic abnormalities. The findings of the general medical examination (which was routinely done at the first prenatal visit) were reviewed to determine if the chest abnormalities would have been suspected from the results of physical examination alone. In every case, a positive history or abnormal physical finding would have suggested the presence of the major abnormality or of the need for roentgenography to be performed.
