18F-PSMA-11 PET/CT for prostate cancer: Piron and colleagues evaluate the administration safety and radiation dosimetry of 18F–prostate-specific membrane antigen–11 in patients with suspected prostate cancer recurrence after previous treatment. Page 1736

Featured Article of the Month—Imaging fibroblast activity after MI: Varasteh and colleagues investigate the feasibility of PET imaging of activated fibroblasts with a new 68Ga-labeled fibroblast activation protein inhibitor in a preclinical model of myocardial infarction. Page 1743

Imaging acute doxorubicin cardiotoxicity: McCluskey and colleagues evaluate an 18F-labeled lipophilic phosphonium cation as a cardiac imaging agent, comparing it with PET and SPECT tracers to assess utility for imaging cardiotoxicity in an acute doxorubicin model. Page 1750

Dopamine in atypical parkinsonism: Kaasinen and colleagues conduct a metaanalysis of striatal presynaptic dopaminergic function imaging in multiple-system atrophy parkinsonism and cerebellar variants, progressive supranuclear palsy, corticobasal syndrome, and Parkinson disease. Page 1757
