Design outcomes

Primary

Measure	Time frame
The aim of the retrospective analysis is to determine the biodistribution of the GRPR ligand 99mTc-BTG-N4 and in particular the radiation dose for organs and the whole body. time period: 05.07.2021 - 20.07.2022 Method: The "Volume of Interest" is drawn around the corresponding organs and the activity concentration in the different acquired images is determined. Other clinical parameters and the activity values show the residence time of the radiopharmaceutical in the individual organs.	—
