Objective: The hepatic arterial buffer response is a well-known phenomenon in hepatic circulation, describing the response of hepatic arterial resistance to changes in portal vein flow. Several ...

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 ...

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.

Given the potential risk of X-ray radiation to the patient, low-dose CT has attracted a considerable interest in the medical imaging field. Currently, the main stream low-dose CT methods include ...

Myocardial perfusion imaging (MPI) is an important imaging modality in the management of patients with cardiovascular disease. MPI plays a key role in diagnosing cardiovascular disease, establishing ...

Perfusion imaging by CT and MRI were found to be unnecessary for safe and effective triage of patients with severe ACOs. An algorithm was adopted that includes: non-contrast CT to identify hemorrhage ...

The Diffusion and Perfusion Imaging Evaluation for Understanding Stroke Evolution (DEFUSE) [125, 126] trial was a prospective, multicenter study, which recruited 74 stroke patients treated with ...

Mean systolic BP rates at 1 hour were significantly lower for the intensive treatment group compared to the guideline group (149.6 mm Hg vs 158.8 mm Hg, respectively; P < .0001). Poor physical ...

EXECUTIVE SUMMARY In the last decade, myocardial perfusion imaging (MPI) with PET has emerged to play a pivotal role in the clinical routine process for the detection of hemodynamically significant ...

We excluded patients who underwent repeated imaging because imaging from the referring hospital was unavailable, of insufficient quality, or incomplete, including the need to perform CT perfusion in ...

High blood pressure after intracerebral hemorrhage (ICH) is associated with hematoma expansion, aggravation of perihematomal edema, and poor clinical outcome. 1 – 3 The American Stroke Association ...
