Implication

Establishes MRI measurement precision benchmarks for carotid arteries; extends technical validation for research but leaves clinical adoption open.

Key Points

To assess the measurement precision and repeatability of arterial lumen and wall area quantifications using high-resolution MRI in patients with carotid atherosclerosis.
Performed two independent high-resolution MRI scans at the carotid bifurcation across 8 patients within a two-week interval.
Evaluated measurement variability across T1-weighted, proton density-weighted, and T2-weighted image sequences.
Lumen area measurement error was 6.2% for T1-weighted, 9.2% for proton density, and 9.7% for T2-weighted images.
Wall area measurement error was 10.8% for T1-weighted, 10.9% for proton density, and 12.0% for T2-weighted images, with precision strongly correlating with overall image quality.
