Estimation of the uteroplacental perfusion by use of 113mIn-transferrin and an iterative regression method.
For the clinical evaluation of the uteroplacental blood flow the radioactivity curve over the placenta is recorded by means of a gamma scintillation camera and is calculated by iterative regression method. The flow curves were attributable with good clinical relevance to 3 perfusion types: perfusion type I indicates unimpaired uteroplacental flow. Type II is a transitional type to the pathological type III. Over two-thirds of the type III cases gave births to babies with signs of moderate to severe malnutrition and in 1 case an intrauterine death occurred.
