[Use of nuclear-medicine technics in the differential diagnosis of anemias].

The use of nuclear-medical methods is especially described for the diagnostic of anaemias with different etiology. For the diagnosis of the chronic haemorrhagic anaemias the determination of the blood losses through the gastrointestinal tract with the help of the 51Cr-method and for the course of the acute haemorrhagic anaemias the automatized determination of the blood volume are emphasized. For the proof of a latent haemolysis often the knowledge of the apparant half survival time of the erythrocytes is necessary. Also in manifest haemolysis this investigation method gives differential-diagnostic references. For the megaloblastic anaemias a diagnostic routine programme and a differentiated investigation scheme are reported by Hoffbrand. For the clarification of the anaemias by insufficiency of the bone-marrow and ineffective erythropoiesis the radio-iron-kinetic investigations have proved. They should also be taken into consideration for the indication of the transplantation of the bone-marrow.
