Summary: The results in 70 patients studied by indium‐113m for placental localization using a scanner or gamma camera are presented. This method is reliable, safe, and convenient. The radiation exposure to the mother and fetus is very much less than with radiological methods. The diverging collimator provides a valuable addition to the gamma camera methods previously described. Difficulties in the diagnosis of minor degrees of placenta praevia are often due to problems in defining the position of the lower segment and possibly to changes which occur in the lower segment in late pregnancy:
