Comparison of bulk flow measurements in the large vessels between four-dimensional flow (4D-flow) and two-dimensional phase contrast (2D-PC) magnetic resonance imaging (MRI)
Bulk flow measurements in large vessels are clinically consistent between 4D-flow and 2D-PC MRI.
4D-flow demonstrates systematic undermeasurement compared to 2D-PC in large cohorts.
The study analyzed data from various large vessels using both MRI techniques to assess flow measurements.
These findings may indicate the need for further validation of 4D-flow accuracy against 2D-PC MRI.
Abstract
Bulk flow measurements in the large vessels were grossly clinically consistent between 4D-flow and 2D-PC in this large cohort study, although 4D-flow showed systematic undermeasurement compared with 2D-PC.
