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.

THURDAY, June 26, 2025 (HealthDay News) — Neither computed tomography (CT) perfusion nor CT angiography meet the prespecified validation threshold as an ancillary test for death by neurologic criteria ...

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 ...

Regional perfusion monitoring, often performed by pulmonary perfusion computed tomography, is vital in intensive care units. Electrical impedance tomography, repeatable and of non-invasive nature, ...

A NEW study has developed a machine learning (ML) model capable of predicting lung perfusion in pulmonary embolism (PE) patients using non-contrast computed tomography (CT) scans. This approach could ...

Kevin Sheth, MD, discusses the role of computed tomography perfusion amid stroke diagnosis.

Latest generation computed tomography scanners (≥ 64 slices) allow the possibility of performing static or dynamic perfusion imaging during stress by using coronary vasodilator agents (adenosine, ...

A research team from Lille University Hospital in France has recently demonstrated that dual-energy computed tomography lung perfusion can provide valuable additional information for standard CT scans ...

Background: Definitive diagnosis of acute ischemic stroke is challenging, particularly in telestroke settings. Although the prognostic utility of CT perfusion (CTP) has been questioned, its diagnostic ...

Computed Tomography Protocol and Image Reconstruction All swine were scanned on a wide-coverage, 256-row (16 cm in z -axis) CT scanner (Revolution CT, GE Healthcare, Milwaukee, WI, United States) with ...

Objective: To investigate the spectral and perfusion computed tomography (CT) findings of peripheral lung cancer (PLC) and focal organizing pneumonia (FOP) and to compare the accuracy of spectral and ...
