216 NORTH CAROLINA MEDICAL JOURNAL March, 1968 Fig. 1. Technique for marking the uterus. Fig. 2. Normally implanted placenta. Fig. 3. Placenta previa. Then the patient must be given Lugol's solution prior to the procedure to reduce the radiation to the fetal thyroid. Clinical Applications and Results Radioisotope placentography is principally employed in the evaluation of third trimester bleeding. It is one of the most reliable procedures for placenta localization, with most authors reporting an accuracy slightly greater than 95%. Johnson, et al.2 reported an accuracy of 96.4% in 86 cases. The major difficulty in localizing the placenta by means of this procedure is encountered when the placenta is implanted posteriorly. Conclusion Radioisotope placentography affords the clinician a simple, accurate procedure, with an extremely low radiation exposure to the fetus as well as the mother, for the evaluation of third trimester bleeding. Placenta Localization Indications: Third trimester bleeding Patient preparation: With 131I HSA, Lugol's solution prior to the procedure. None is required with the other radiopharmaceuticals. Time required for procedure: Fifteen to 20 minutes Radiation dose: Considerably less than with x-ray placentography. Value of procedure: 95% accurate Limitations: Posterior implantations are often dificult to localize. References Browne, J. C.
