Analysis reveals differences in regional ventilation and perfusion in lungs using 0.55T and 1.5T MRI systems, indicating significant advantages for low field imaging.
Key Points
The study demonstrates the benefits of using a 0.55T MRI system for lung imaging, showing improved results for ventilation and perfusion.
Results indicate that low field MRI systems can provide effective measurements of regional fractional ventilation and perfusion.
Time-resolved ultra-fast balanced steady state free precession datasets were acquired from six healthy volunteers to assess imaging performance.
Findings suggest that the gradient performance of the MRI system impacts the acquisition of lung functional metrics, favoring the 0.55T system.
