The clinical impact of phase offset errors and different correction methods in cardiovascular magnetic resonance phase contrast imaging: a multi-scanner study
Background: Cardiovascular magnetic resonance (CMR) phase contrast (PC) flow measurements suffer from phase
offset errors. Background subtraction based on stationary phantom measurements can most reliably be used to
overcome this inaccuracy. Stationary tissue correction is an alternative and does not require additional phantom
scanning. The aim of this study was 1) to compare measurements with and without stationary tissue correction to
phantom corrected measurements on different GE Healthcare CMR scanners using different software packages and
2) to evaluate the clinical implications of these methods.
Methods: CMR PC imaging of both the aortic and pulmonary artery flow was performed in patients on three
different 1.5 T CMR scanners (GE Healthcare) using identical scan parameters. Uncorrected, first, second and third
order stationary tissue corrected flow measurement were compared to phantom corrected flow measurements, our
reference method, using Medis QFlow, Circle cvi42 and MASS software. The optimal (optimized) stationary tissue
order was determined per scanner and software program. Velo

Reference ranges ("normal values") for cardiovascular magnetic resonance (CMR) in adults and children: 2020 update
Cardiovascular magnetic resonance (CMR) enables assessment and quantification of morphological and functional parameters of the heart, including chamber size and function, diameters of the aorta and pulmonary arteries, flow and myocardial relaxation times. Knowledge of reference ranges ("normal values") for quantitative CMR is crucial to interpretation of results and to distinguish normal from disease. Compared to the previous version of this review published in 2015, we present updated and expanded reference values for morphological and functional CMR parameters of the cardiovascular system based on the peer-reviewed literature and current CMR techniques. Further, databases and references for deep learning methods are included
