Rapid Scintiphotographic Placental Localizations Utilizing Free ^99mTc Pertechnetate¹

San Francisco, California

ABSTRACT

The use of free ^99mTc-pertechnetate ion for placental localization was evaluated in 18 patients in the third trimester of pregnancy. Unequivocal localization and imaging of the placenta was performed with 300 µCi^99mTc within five minutes after injection of the pertechnetate bolus. This rapid and precise localization of the placenta is accomplished through use of the Anger-type scintillation camera to image the initial vascular distribution of the pertechnetate bolus in the placenta. Fetal radiation is very low, i.e., 5 mr or less.
