Scintigraphy of the Placenta With {sup 113m}In

Abstract

The paper describes the merits of using {sup 113m}In in scintigraphic placental localization. The {sup 113m}In, generated from a commercial {sup 113}Sn cow, eluted with 0.05N HC1, stabilized with gelatin at pH 4.0 and autoclaved in the carrier-free form, becomes bound to the plasma proteins after being injected intravenously and stays in the vascular system long enough to enable scanning of the placental blood pools. The short physical half-life and the decay by isomeric transition reduces the radiation dose compared with other scanning agents. The minimal elimination of the molecule into the bladder during scanning has the advantage over the use of {sup 99m}Tc because it diminishes the possible confusion of activity in this area with a low-lying placenta. The placentography has been found of value in the diagnosis of placenta praevia, twins and hydatidiform mole. (author)
