Optimization of Radiation Applications in Medicine

Our mission is improving the efficiency of medical applications of ionising radiation. The research focus of our working group is to make personalised applications of ionising radiation in medicine in an efficient way with regard to medical diagnostic and therapeutic procedures. Scientific strengths of our working group are the expertise in biokinetic modelling, imaging geometries and tomographic reconstruction methods as well as uncertainty and sensitivity analysis.

"Preclinical experiments on nuclide distribution, pharmacokinetic modelling and internal dose estimation in radionuclide therapy with alpha emitters"
Coordination: Dr. Kerstin Hürkamp
Project members: Dr. Weibo Li, Samaa Saleh

The aim of the project is to optimise the use of alpha emitters in radionuclide therapy. In preclinical experiments with 225Ac-PSMA I&T, we

  • determine the nuclide distribution of 225Ac and its progeny bound to the carrier substance PSMA I&T or as low molecular weight compounds in representative organs and tissues, blood, urine and in the tumour at different time points after injection,
  • develop a pharmacokinetic model for 225Ac-PSMA I&T and its downstream products, which also takes into account a possible separation of the radiopharmaceutical from the carrier substance,
  • calculate the internal dose (energy and organ equivalent doses) and compare the results with published data.
