Insights into how the heart recovers after myocardial infarction (heart attack) can be obtained with a new radiotracer that targets fibroblast activity prior to it causing permanent damage. According to research published in the December issue of The Journal of Nuclear Medicine, 68Ga-FAPI-04 positron emission tomography (PET) can effectively image fibroblast activation after myocardial infarction, identifying a time window during which cardiac fibrosis can be prevented and the disease course altered.
