Inter\u2010 and intraexaminer reliability were determined using intraclass correlation coefficients (ICC), and discriminative performance was analyzed via area under the receiver\u2010operating characteristic curve (AUROC). Both PI\u2010LTC and QHI demonstrated strong discrimination (AUROC 0.85\u20131.00). The QHI showed the highest and most consistent reliability (ICC \u2248 0.65\u20130.75), whereas the PI\u2010LTC achieved higher sensitivity but moderate reproducibility (ICC \u2248 0.50), particularly in posterior regions. The MGI yielded fair to good reliability (ICC \u2248 0.45\u20130.55) and was more examiner dependent.
