Sedatives, facial trauma, or metabolic disturbances can cloud that picture. Many centers have turned to computed-tomography flow imaging, betting that a scan can settle what the stethoscope cannot. In ...

Probably the best CT-based marker for the infarct core is a low-blood-volume abnormality identified in cerebral blood volume maps derived from CT perfusion data, [48] which is discussed later.

Background: CT Perfusion (CTP) defined hemodynamic parameters used to delineate admission infarct core can be affected by truncated data acquisition, recanalization status and reactive hyperemia. We ...

The field of nuclear cardiology is witnessing growing interest in the use of cardiac PET for the evaluation of patients with coronary artery disease (CAD). The available evidence suggests that ...

Methods This retrospective study collected CT perfusion data at admission for AIS patients receiving MT over 6 hours after symptom onset, from January 2020 to December 2024, across three centers.

Background The purpose of this study was to evaluate the correlation between a novel angiographic score for collaterals and CT perfusion (CTP) parameters in patients undergoing endovascular treatment ...

Sequential testing by coronary CT angiography (CTA) and myocardial perfusion SPECT (MPS) obtained on stand-alone scanners may be needed to diagnose coronary artery disease in equivocal cases. We have ...

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 perfusion and CT angiography did not meet sensitivity and specificity thresholds of 98% to determine death by neurologic criteria (commonly referred to as brain death), a cohort study showed.

A heat advisory is in effect for most of the region today, "with heat index values climbing to between 95 and 100," according to the National Weather Service branch in Norton, MA. The advisory ...

BACKGROUND: Direct reprogramming of fibroblasts to cardiomyocytes is a potentially curative strategy for ischemic heart ...
