Core tip: Dual-energy derived iodine maps and dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) may allow evaluation of pulmonary perfusion. Hypothetical the decrease in pulmonary perfusion detected on DCE-derived iodine maps would correlate highly with perfusion parameters derived from DCE-MRI in patients with restricted pulmonary perfusion. However, against our hypothesis, we did not find a significant correlation between pulmonary perfusion defects detected on dual-energy computed tomography-derived iodine maps and perfusion parameters derived from time-resolved MRI. In addition, there was only a moderate level of visual correlation. This is in contrast with prior studies that investigated the role of pulmonary iodine maps to serve as an additional tool providing a functional evaluation of pulmonary perfusion.
