Phosphor 32 zerfall
WebDie Radiophosphortherapie ist eine Radionuklidtherapie bei der Polycythaemia vera und der essentiellen Thrombozythämie. Es wird das Radionuklid 32 Phosphor verwendet. Die Methode gilt als Alternative zu den herkömmlichen Behandlungsverfahren – aufgrund ihres Nebenwirkungsprofils aber vorwiegend bei älteren Patienten über 65 oder 70 Jahren.
