[Optimization of T-weighted Imaging Parameters in MR Carotid Plaque Imaging: Influence for the Quantitative Evaluation among Different MRI Scanner Types].

Carotid artery plaques with high-signal intensity on T weighted image (T WI) are known to cause cerebral ischemic disease. Signal intensity ratio (SIR), which is calculated from T WI in the quantitative evaluation of plaque characterization have been used. However, the various sequences in T WI and difference in the sequences were utilized among institutions.
