18F FDG and 68Ga FAPI PET/MR Imaging of Carotid Artery Plaque Vulnerability: A Clinical Study in Carotid Artery Plaque Patients
Recruiting now
Conditions studied: Carotid Artery Plaque, Ischemic Stroke, PET / MR
In brief
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
