BACKGROUND AND PURPOSE: There is a desire within many institutions to reduce the
radiation dose in CTP examinations. The purpose of this study was to simulate dose …

Purpose To quantitatively assess whether decreasing total radiation dose of the image
acquisition protocol has an effect on cerebral CT perfusion values in patients with acute …

Background and purpose Brain CT Perfusion (CTP) is an X-ray imaging technique for the
assessment of brain tissue perfusion, which can be used in several different entities. The …

Objectives To investigate the feasibility of 70 kV cerebral CT perfusion by comparing image
quality and radiation exposure to 80 kV. Methods Thirty patients with suspected cerebral …

BACKGROUND AND PURPOSE: Despite common use of CTP to assess cerebral
hemodynamics in the setting of ischemia, concerns over radiation exposure remain. Our aim …

Purpose To examine CTP of the brain in real patient data after reducing tube current down to
80 mAs to decrease radiation dose. Methods CTP was acquired in 60 suspected stroke …

Perfusion CT (PCT) of the brain is widely used in the settings of acute ischemic stroke and
vasospasm monitoring. The high radiation dose associated with PCT is a central topic and …

OBJECTIVE. The purpose of this study was to measure the organ doses and estimate the
effective dose for the standard brain perfusion CT protocol and erroneous protocols …

Objectives To examine the impact of denoising on ultra-low-dose volume perfusion CT (ULD-
VPCT) imaging in acute stroke. Methods Simulated ULD-VPCT data sets at 20% dose rate …

Purpose We aimed to compare different computed tomography (CT) perfusion post-
processing algorithms regarding image quality of perfusion maps from low-dose volume …
