Phase contrast (PC) MR flow measurements are affected by multiple sources of error, including background phase offsets. The gold-standard approach to correct these offsets involves repeating PC measurements on a static phantom, prolonging each CMR study and impeding exam workflow. Here, we compared the performance of a self-calibrated correction to static-phantom corrected PC data obtained from a pediatric and congenital heart disease population. Self-calibrated correction results showed strong agreement with phantom-corrected data for all vessel types and differed from static-phantom correction by a mean difference in Qp/Qs values of only 0.069.
