N2 - 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.
