Phase-resolved functional lung (PREFUL) MRI is a very promising method for contrast agent free pulmonary perfusion measurement in free breathing. Still a large-scale validation of quantified pulmonary blood flow (PBFPREFUL) with the current gold standard PBFDCE derived by dynamic contrast enhanced (DCE) MRI is missing. Therefore, 52 patients with COPD, CF and CTEPH were included in this study and the correlations for PBFPREFUL and PBFDCE were assessed. Except for CTEPH, strong and moderate correlations were found. Low or no correlation can be explained by respiratory motion (DCE) and perfusion delay (PREFUL).
