Key Points

This study aims to assess the diagnostic effectiveness and reliability of cortical thickness measurements and CT angiography in diagnosing brain death.
Retrospective analysis of 42 brain death patients and 144 healthy controls.
Measurements of precentral gyrus cortical thickness in both brain hemispheres.
4-point computed tomography angiography scoring by blinded radiologists.
ROC curve analysis for cutoff values and diagnostic metrics.
Evaluation of observer reliability using ICC, Cohen's Kappa, and Bland-Altman methods.
4-point CTA demonstrated 97% accuracy, 88% sensitivity, and 100% specificity.
Cortical thickness measurement showed approximately 90% sensitivity, specificity, and accuracy.
Observer agreement was excellent with ICC values ranging from 0.988 to 0.999.
