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

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 ...

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 ...

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 ...

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 ...

Whole-brain CT imaging, without the administration of contrast material was followed by CT perfusion imaging, comprising two 60-second series, each performed after an intravenous bolus of 40 ml of ...

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 ...
