CT perfusion and angiography failed to meet sensitivity and specificity thresholds to determine brain death. Neither should be used as standalone tests to establish death by neurologic criteria, the ...
Brain death determination sits at the fraught intersection of critical-care medicine, ethics, and organ-donation logistics. Missteps risk either prolonging mechanical support with no prospect of ...
Near-infrared spectroscopy, or fNIRS, offers a way to monitor brain activity without surgery or radiation by tracking changes in blood flow and oxygenation. Light sources placed on the scalp send near ...
A brain-dedicated scanner is changing what doctors can see. CT researchers say that ‘opens the door’
At the Yale Positron Emission Tomography Center, an ultra-high-performance brain-dedicated scanner called the NeuroEXPLORER, or NX, is redefining what is possible in brain PET imaging. With a 10-fold ...
Death has always puzzled humans. We know the body slows, breathing changes, heartbeat weakens, limbs cool. But what does the brain do in those final moments? Recent scientific studies give us insight ...
