PET/CT may have found cardiovascular event trigger
PET/CT scans have identified activity in a stress-related structure in the brain that could be linked to an increased risk of cardiovascular disease, according to a study published online January 11 in the Lancet.

Researchers from Massachusetts General Hospital (MGH) and the Icahn School of Medicine at Mount Sinai discovered a pathway leading from the amygdala, which is the apparent activation site, through elevated immune system activity to an increased incidence of cardiovascular events.

The researchers made their discoveries through two complementary studies. The study conducted at MGH analyzed imaging and medical records from approximately 300 patients who underwent FDG-PET/CT brain imaging primarily for cancer screening. All participants had no active cancer or cardiovascular disease at the time of imaging...
