Using Multi-tracer to early diagnosis of therapy-associated cardiotoxicity using multimodality PET/MRI.

In this study investigators evaluated cardiac uptake by different molecular probe such as FDG, FAPI-04 using multimodality PET/MRI. Previous studies have shown that increased cardiac uptake of FDG on PET may be an indicator of myocardial injury after chemotherapy. Cardiac magnetic resonance (CMR) allows for multiparametric evaluation of cardiac morphology, ventricular function, myocardial perfusion, and viability. The combination of PET with MR (PET/MR) is therefore an alternative attractive pairing for diagnostic imaging. The aim of this study is to find noninvasive and effective method for early diagnosis of cardiotoxicity after chemotherapy or immunotherapy
