In plain words

What the trial is, and whether it could suit you

Carotid atherosclerotic plaque rupture is the main cause of ischemic stroke attacks, and early and precise assessment of plaque vulnerability can prevent ischemic stroke. High-resolution MRI can reflect vulnerable plaque features such as thin fibrous caps and large lipid cores, but cannot assess their metabolic information; Fibro-activated proteins (FAPs) of PET are specifically expressed in atherosclerosis and suggest vulnerable plaques by reflecting inflammation-induced fibrosis. The aim of this study was to apply 18F FDG\&68Ga-FAPI PET/MR imaging to investigate the vulnerability of carotid atherosclerotic plaques, to obtain quantitative evaluation indexes of active fibrosis within carotid plaques, and to clarify the PET/MR characteristics of unstable plaques in carotid arteries
