About this trial
In this study the investigators aim to examine the role that fibrosis plays in heart conditions such as aortic stenosis , chemotherapy-induced cardiotoxicity and carcinoid syndrome . Fibrosis is a common final result following any injury to the heart muscle and the investigators aim to identify this process early and in its active state. This will be examined by using a radiotracer 68Ga-FAPI or 18F-AlF-FAPI and PET-MRI or PET-CT.
