Measurement accuracy of atherosclerotic plaque structure on CT using phantoms to establish ground truth

摘要

Rationale and objectivesThe purpose of this study was to characterize analytic performance of software-aided arterial vessel structure measurements across a range of scanner settings for CT angiography (CTA) where ground truth is known. We characterized performance for measurands which may be efficiently measured for clinical cases without use of software as well as those which may be done manually but which is generally not done due to the effort level required unless software is employed.
