Delayed Ga-FAPI-46 PET/MR imaging confirms ongoing fibroblast activation in patients after acute myocardial infarction.

Purpose Of The Report: Combined cardiac Ga-Fibroblast-Activation Protein-alpha inhibitor (FAPI) positron-emission tomography (PET) and cardiac magnetic resonance imaging (MRI) constitute a novel diagnostic tool in patients for the assessment of myocardial damage after an acute myocardial infarction (AMI). Purpose of this pilot study was to evaluate simultaneous Ga-68-FAPI-46-PET/MR imaging in the delayed phase after AMI.

Material And Methods: Eleven patients underwent hybrid Ga-FAPI-46 PET/MRI post AMI.

[Hybrid imaging in prostate cancer : Status quo and future applications].

Background: Recently, the use of prostate-specific membrane antigen (PSMA) tracers like 68Ga-PSMA-11 in positron emission tomography (PET) have shown promising results and are helping to improve care for patients with prostate cancer (PC).

Purpose: In the following we review the current literature on PSMA-ligand PET, in particular with regard to the currently increasing replacement of 68Ga-PSMA ligands by 18F-labeled PSMA ligands.

Results: PSMA-ligand PET is most frequently used for biochemical recurrence.
