Heart blood flow print8/11/2023 ![]() Mean difference in split blood flow by Bland–Altman analysis was 0.79% with 95% limits of agreement (-11.2 to 12.8%). ResultsĬorrelation between split blood flow measured by scintigraphy and MRI using net flow was 0.90 (95% CI: 0.83–0.94, P < 0.001) and the ICC for agreement on split blood flow was 0.90 (95% CI: 0.84–0.94). Agreement was calculated using interclass correlation coefficient (ICC) for absolute agreement and Bland–Altman difference analysis. Pearson’s correlation coefficient was used to determine the relationship between split blood flow measured by the two examinations. Patient demographics, medical/surgical information, and estimates of split blood flow by both modalities were recorded. ![]() We performed a retrospective review of patients < 21 years of age who had undergone both nuclear medicine pulmonary perfusion scans (Tc-99 m MAA) and cardiac MRI examinations from January 2012 to August 2021 at our tertiary pediatric hospital. To assess agreement of pulmonary blood flow measurements obtained by scintigraphy and MRI in children and young adults. Minimally invasive imaging of pulmonary blood flow can be achieved with scintigraphy or magnetic resonance imaging (MRI). Split blood flow via the pulmonary arteries guides and demonstrates the effect of interventions. Measurement of differential blood flow to the lungs is important to understanding flow dynamics in the setting of congenital heart disease.
