Goodbye to Fick’s law

It has always been assumed but never proven that iCMR gives an incremental value by providing more accurate flow quantification. In Dallas Childrens/UTSW interventional MRI is now standard procedure in young adults. Therefore they conducted a study in 30 patients with CHD and conducted both right and left heart cath at a success rate of multiple data points of 98 %. In doing the study the Dallas team validates hemodynamic measurements obtained via iCMR and showed that iCMR-derived flows have considerably higher test–retest reliability for Qs. iCMR evaluations allow for more reproducible hemodynamic assessments in the CHD population.
