Ammar Alfteimi, Ulf Lützen, Alexander Helm, Michael Jüptner, Marlies Marx, Yi Zhao, Maaz Zuhayra Abstract Background: The recent development of quinoline-based radiotracers, which act as fibroblast activation protein inhibitors (FAPIs), has shown promising preclinical and clinical advantages. [68Ga]Ga-FAPI-46 is a new radiotracer for in [...]

Torsten Kuwert, Christian Schmidkonz, Olaf Prante, Georg Schett, Andreas Ramming Abstract: In vivo visualization of inflammatory lesions in the body has been revolutionized by positron emission tomography (PET) with F-18-deoxyglucose (FDG) as a tracer and by magnetic resonance imaging (MRI) with gadolinium-labelled contrast media. Apart [...]
