To detect in-stent restenosis among patients with coronary stents, a new study shows the potential for improved diagnostic accuracy by adding computed tomography perfusion imaging to coronary CT ...

This study aimed to evaluate the diagnostic performance of combined dynamic stress CT myocardial perfusion imaging (CTP) and coronary CT angiography (CTA) alongside CT-derived fractional flow reserve ...

In 2015 approximately 15.9 million myocardial infarctions occurred worldwide 1. Thereby ischemic heart disease is the most common cause of death (7.249 million deaths worldwide in 2008) accounting for ...

Trials of endovascular therapy for ischemic stroke have produced variable results. We conducted this study to test whether more advanced imaging selection, recently developed devices, and earlier ...

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 ...
