We evaluated the image quality and diagnostic performance of late iodine enhancement CT (LIE-CT) reconstructed with a knowledge-based iterative model reconstruction (IMR) for the detection of myocardial infarction (MI) assessed by late gadolinium enhancement magnetic resonance imaging (LGE-MRI) in comparison with filtered back projection (FBP) and hybrid iterative reconstruction (HIR).
Efficacy
Image quality score (visual score, signal to noise ratio, contrast to noise ratio)
Diagnostic performance for detecting MI (sensitivity, specificity, positive predictive value, negative predictive value)
Image noise
CT attenuation difference between remote and infarcts myocardium
Reproducibility of diagnostic performance for detecting MI
Correlation in %MI volume between CT and MRI
