title: [Comparison of simple nuclear medical methods of determining renal clearance].
abstract: Comparative clearance determinations with a partially shielded whole-body counter, a shoulder probe, a gamma camera and also exclusively by use of the plasma activity concentration at 45 min p.i. revealed the following results: The partially shielded whole-body counter can be substituted by the shoulder probe without major loss of quality, provided that this is taken into consideration in the subsequent calculations. However, values below 250 ml/min may possibly be wrong, i.e. too high, when the camera background-curve is used for clearance determination. The very simple 45-min-clearance is recommended mostly as a method in addition or in reserve.
