18F FDG and 68Ga FAPI PET/MR Imaging of Carotid Artery Plaque Vulnerability: A Clinical Study in Carotid Artery Plaque Patients
Source: ClinicalTrials.gov · Last updated 5 Mar 2026
Brief summary (registry, in English)
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

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Other illness
- Absolute or relative contraindications related to PET/MR imaging safety (e.g., metallic implants, MRI phobia, etc.); Patients who have undergone carotid endarterectomy (CEA) or carotid artery stenting (CAS); Pregnant or lactating women; Presence of other vascular diseases, such as vasculitis, moyamoya disease, arterial dissection, etc.; Severe agitation or inability to cooperate with imaging procedures.
Who the study is looking for
- -Age between 18 and 80 years; Presence of carotid atherosclerotic plaque confirmed by ultrasound within the past two weeks, with carotid intima-media thickness (IMT) ≥ 2 mm (IMT ≥ 1.2 mm is defined as carotid atherosclerosis) or carotid artery stenosis ≥ 50% as indicated by CTA.
