1961 Obstetr. & Gynecol. 18 405/2 Despite all attempts to reduce the radiation dosage, it was calculated that 250–750 mr. were being delivered to the maternal ovaries and the fetus at the time of each placentogram.

1971 Obstetr. & Gynecol. 37 604/1 Of the 84 patients on whom a placentogram was taken, painless third-trimester vaginal bleeding was the most common indication for the study (50 of 84).

1975 A. E. James et al. in E. J. Potchen Current Concepts in Radiol. II. xi. 304 We have found a decrease in the number of placentograms performed, and an increased use of sonography in this circumstance.
