. Placental scintigraphy with 113m In (Indium) combined with cervical marking with a shielded 57 Co (Cobalt) radioactive source is easy to perform and causes no harm to the patient. The radiation dose to mother (gonads, about 15 mrad) and fetus (about 10 mrad) is extremely low. A total of 111 patients have been examined. The method provides accurate results in localizing the placenta. Low implantation or placenta praevia were diagnosed in 45 patients. Scintigraphic evaluation of disturbances in placental blood flow has given promising results (16 patients). In a great number of cases it has been possible to avoid unnecessary and expensive hospitalization by excluding placenta praevia as cause of vaginal bleeding. It is a reliable method for localizing the placenta before diagnostic amniocentesis.
