FPRNA tended to over-estimate RVEF. Correlation between RVEFs from CARDIAC MR and FPRNA was 0.5. Correlation between LVEFs from CARDIAC MR and MUGA was 0.9. The degree of discrepancy in RVEF between FPRNA and CARDIAC MR was statistically significant (p = 0.006) relative to the degree of discrepancy in LVEF between MUGA and CARDIAC MR
