title: Placental radioangiography as a method for the study of uteroplacental blood flow in the rhesus monkey.
abstract: Placental radioangiography was performed in lightly anesthetized, pregnant rhesus monkeys under close monitoring of vital signs. Two angiographies in the same animal performed at an interval of approximately 20 min consistently produced identical patterns but not at intervals of one or two weeks. Evidence is adduced that the parameters, calculated from the angiograms, represent indices of uteroplacental blood flow under the standardized conditions of the angiographic procedure described here. Thus, placental radioangiography constitutes a relatively simple procedure for comparative, semiquantitative studies.
