Key result
High-resolution MRI demonstrated substantial intraobserver agreement for identifying carotid plaque calcifications (kappa 0.70) and hemorrhages (kappa 0.82), but fibrous cap agreement was fair.

Does high-resolution MRI provide reproducible identification and quantification of carotid atherosclerotic plaque components in patients with carotid artery stenosis?
Population
85 consecutive patients with symptomatic or asymptomatic carotid artery stenosis
Design

Supports high-resolution MRI for carotid plaque research; leaves open clinical adoption due to fair fibrous cap agreement.
Observational (n=85)
Does high-resolution MRI provide reproducible identification and quantification of carotid atherosclerotic plaque components in patients with carotid artery stenosis?
Effect estimate: kappa 0.70 (95% CI 0.54-0.86)
High-resolution MRI provides acceptable reproducibility for quantifying vessel and plaque components, though variability exists, particularly for fibrous cap identification.
Touzé et al. (2007) conducted an observational in Carotid artery stenosis (n=85). High-resolution MRI was evaluated on Intraobserver and interobserver agreement for the identification of carotid atherosclerotic plaque components (kappa 0.70, 95% CI 0.54-0.86). High-resolution MRI demonstrated substantial intraobserver agreement for identifying carotid plaque calcifications (kappa 0.70) and hemorrhages (kappa 0.82), but fibrous cap agreement was fair.
