Hypothesis
How does slice thickness affect MR flow quantification in turbulent jets?
Conclusion
Slice thickness significantly influences flow quantification in turbulent flow, and adjusting flow encoding parameters can help reduce errors.
Supporting Evidence
- Flow deviations were measured for different slice thicknesses and imaging settings.
- Maximum flow underestimation occurred with a specific RF pulse duration and flow encoding gradient strength.
Takeaway
The thickness of the slice in MRI can change how accurately we measure blood flow, especially when the flow is turbulent.
Methodology
A flow phantom was used to simulate aortic stenosis, and various MR imaging settings were tested to measure flow deviations.
Limitations
Further investigations are needed to fully understand the impact of slice thickness on flow quantification in real patients.
