Abstract
Introduction
Velocity offset errors may influence flow measurement in phase-contrast cardiovascular
magnetic resonance (CMR). By using a stationary gel phantom, offset errors probably
may be corrected. We tested its impact on flow measurement and, in particular, on
shunt calculation in patients proven not to have any shunt.
Methods
Flow measurements were carried out in 24 patients with congenital heart disease. Baseline
correction was performed by using a stationary gel phantom.
Results
Significantly more patients without shunts incorrectly showed a calculated shunt after
baseline correction.
Conclusions
Baseline correction did not improve flow measurement and was clinically not relevant
for routine CMR.
