CT perfusion had a higher sensitivity than MR perfusion based on the secondary reference standard (p < 0.01), but a lower specificity than MR using the primary reference standard (p < 0.01). The ...

Qualitative whole-brain CT perfusion achieved 93.6% sensitivity and 92.3% specificity. CT angiography sensitivity ranged from 75.5–87.3%, while specificity held near 90% across scales.

Neither computed tomography (CT) perfusion nor CT angiography meet the prespecified validation threshold as an ancillary test for death by neurologic criteria (DNC) in critically ill patients.

CT angiography sensitivity ranged from 75.5% to 87.3%, and specificity ranged from 89.7% to 91.0%, the researchers reported in JAMA Neurology.The findings were also presented at the Critical Care ...

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 ...

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 ...

A protocol using a second-generation,128-slice dual-source CT scanner with novel high-pitch scanning detected myocardial ischemia quickly and accurately (compared with MRI), while exposing the ...
