This commentary introduces Türkiye's national clinical protocol for neuroradiological ancillary testing in brain death determination, which was developed to address persistent variability in imaging-based practice; it was first published in Turkish (2025) and subsequently translated into English (2026). It outlines a pragmatic national framework for the standardized use, interpretation, and reporting of computed tomography angiography, digital subtraction angiography, and transcranial Doppler ultrasonography while reaffirming that brain death remains a clinical diagnosis. By emphasizing practical examples, structured reporting, common pitfalls, and pediatric considerations, the protocol aims to improve consistency and interpretive reliability while contributing to the broader international discussion on ancillary testing.
Hatipoglu et al. (2026) studied this question.
