Brain death determination sits at the fraught intersection of critical-care medicine, ethics, and organ-donation logistics.

CT perfusion and CT angiography did not meet sensitivity and specificity thresholds of 98% to determine death by neurologic ...

The observed sensitivity and specificity measures for computed tomography perfusion and computed tomography angiography as an ...

Adding stress myocardial CT perfusion imaging to examinations with CT angiography may safely increase diagnostic specificity and reduce the need for invasive treatments in patients with possible ...

CT Perfusion Over CTA. Published online yesterday ahead of print in JACC: Cardiovascular Imaging, the ADVANTAGE study included 163 consecutive stable patients with coronary stents who were referred ...

Comparable diagnostic accuracy. Seeking to address these concerns with CT perfusion, the researchers compared its ability to that of MR perfusion in diagnosing obstructive CAD in a substudy of the ...

In stress testing using regadenoson, CT perfusion imaging resulted in a similar ability to detect or rule out myocardial ischemia, compared with the reference method, regadenoson stress testing ...

Tenecteplase was associated with significantly better reperfusion and clinical outcomes than alteplase in patients with stroke who were selected on the basis of CT perfusion imaging. (Funded by ...

A trial of tenecteplase in patients who had stroke symptoms when they awoke, but who were not selected on the basis of CT perfusion imaging or perfusion–diffusion MRI, showed that tenecteplase ...
