Examination of the uteroplacental hemodynamics was performed on 109 occasions in women admitted to the hospital in the third trimester because of various complications of pregnancy. The radioactive tracer 113m In was injected intravenously and the build‐up and equilibrium times were measured over the placenta, myometrium and heart. The placental build‐up times were most informative, with prolonged values being recorded in about one quarter of these cases. When those extending beyond three minutes were further studied, they were usually found to be associated with severe complications of pregnancy. This did not obtain in cases with shorter placental build‐up times.
