Agreement between single and multiple ROI strategies for hepatic T1 and ECV mapping in tetralogy of Fallot and Fontan circulation
Hepatic native T1 and ECV measurements showed excellent agreement between single-wide and multiple-small ROI strategies in repaired TOF, supporting interchangeable use for longitudinal follow-up. In Fontan patients, concordance between methods was also good, as demonstrated by both ICC and survival-agreement analyses, indicating that either strategy remains feasible; nonetheless, the greater hepatic heterogeneity in this population warrants some caution when comparing measurements obtained with different ROI approaches.
