REDUCTION IN RADIATION EXPOSURE OF CT PERFUSION BY OPTIMIZED IMAGING TIMING USING TEMPORAL INFORMATION OF THE PRECEDING CT ANGIOGRAPHY OF THE CAROTID ARTERY IN THE STROKE PROTOCOL

(1) Background: CT perfusion (CTP) is a fast, robust and widely available but dose-exposing imaging technique for infarct core and penumbra detection.Carotid CT angiography (CTA) can precede CTP in the stroke protocol.Temporal information of the bolus tracking series of CTA could allow for better timing and a decreased number of scans in CTP, resul

How to select and optimize the evaluation indicators from many characteristic information to characterize the internal insulation condition of GIS equipment, and establish a scientific technical and economic evaluation model of insulation condition is a huge challenge needs to be addressed la rams crop top urgently.Motived by this purpose, this stu

Abstract Classification of the Class Echinoidea is under significant revision in light of emerging molecular phylogenetic evidence.In particular, the sister-group relationships within the superorder Luminacea (Echinoidea: Irregularia) have been considerably updated.However, the placement of many families remains largely unresolved due to a series o

We developed a project during an undergraduate course (advanced experimental chemistry) on the microwave-assisted synthesis of biodiesel (BD), via base-catalyzed transesterification of coconut fat (CF) and soybean oil g35 coupe fender (SO) by ethanol, followed by product analysis by gas chromatography/mass spectrometry.Our goals were to introduce a
