Changes and standard errors of means (SEM) in ¹³NH₃ rest MBF based on coronary regions.

Changes and standard errors of means (SEM) in 13NH3 rest MBF based on coronary regions.</p

Rest extraction fraction average and SEM per coronary region determined from DB curve fitting method of DCE-MRI with K^trans divided by MBF from ¹³NH₃.

The extraction fraction average per coronary region for all timepoints was 0.48 ± 0.03 (mean ± standard deviation) for LAD, 0.49 ±0.03 for LCX and 0.53 ± 0.07 for both coronary regions.</p

P-values and Pearson bivariate correlation coefficient of MBF obtained from DB DCE-MRI compared to ¹³NH₃ and to ¹⁸FDG standard uptake values for all time points and coronary regions.

R > 0.75 and R > 0.5 determines strong and moderate positive correlation respectively. Insignificant difference was shown when DB DCE-MRI MBF in different coronary regions were compared (p = 0.06).</p
