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 ...

Three perfusion CT parameters of hepatic perfusion index (HPI), mean transit time (MTT) and permeability-surface area product (PS) were compared among controls, patients and subgroups.

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 ...

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 ...
