[Possibility of quantitative evaluation of renal function based on the renography alone]

Exploring the possibilities of the renal function evaluation on the basis of the renographic curve alone, a theoretical analysis and clinical investigations were carried out. As a result, some indicators of effective renal plasma flow and an indicator of mean transit time were developed. The methods of calculations may serve for a simplified, screening evaluations of renal function, using a simple two-scintillation probe set, as well as computerized camera. The said calculations might constitute a starting point for developing more precise quantitative methods.
