Influencing factors and improvement methods of coronary artery plaque evaluation in CT
Yaqi Gao, Yao Pan, Chongfu Jia
TL;DR
This paper discusses how to improve the accuracy of evaluating coronary artery plaque using CT scans by addressing factors that affect the results.
Contribution
The paper introduces methods to enhance plaque evaluation by addressing inaccuracies caused by CT scan parameters and subjectivity.
Findings
CT value-based plaque evaluation is inaccurate due to luminal attenuation and tube voltage.
Subjectivity and parameter settings significantly affect plaque assessment outcomes.
Improvement methods are needed to enhance the reliability of coronary plaque evaluation.
Abstract
Accurate evaluation of the nature and composition of coronary plaque involves clinical follow-up and prognosis. Coronary CT angiography is the most commonly non-invasive method for plaque evaluation, however, the qualitative and quantitative evaluation of plaque based on CT value is inaccurate, due to the influence of luminal attenuation, tube voltage, parameter setting and the subjectivity.
