Investigation of myocardial extracellular volume fraction in heart failure patients using iodine map with rapid-kV switching dual-energy CT: Segmental comparison with MRI T1 mapping

Myocardial extracellular volume fraction (ECV) from 23 heart failure patients by using dual-energy computed tomography (DECT) and MRI using T1 mapping were compared regionally or segmentally. DECT-ECV map was computed directly from late acquisition projection data, and MRI-ECV map was generated from native and post-contrast T1map using image registration. Mean DECT-ECV and MRI-ECV were 31.6 ± 9.1…
