A new technique for the localization of the cervix at 113mIn placental scintigraphy.
Sixty women in the third trimester of pregnancy were examined with 113mIn placental scintigraphy because of bleeding. In 24 of the cases, the scintigraphic procedure was initiated by application of a Meyers ring containing 113mIn round cervix. In the other cases, the fundus and the symphysis pubis were marked by means of a small radioactive source. Complete placenta praevia was correctly detected in 8 cases and marginal placenta in 4 cases. The scintigraphic localization of the placenta was correct in all the women where the ring was used, whereas when the external marked was used, seven errors occurred. The authors therefore recommend this new technique in order to facilitate the evaluation of the scintigrams.
