Late Gadolinium Enhancement of Nonischemic Cardiomyopathy at 5.0 T versus 3.0 T: A Crossover Design Study

Late Gadolinium Enhancement of Nonischemic Cardiomyopathy Study

Study Overview

This study compares the effectiveness of 5.0-T and 3.0-T cardiac MRI in visualizing late gadolinium enhancement (LGE) in patients with nonischemic cardiomyopathy.

Key Findings

  • No difference in acquisition time: The time taken to obtain images at 5.0 T was similar to that at 3.0 T.
  • Better image quality: 5.0-T images showed superior quality and LGE visualization, especially at 1.2 mm resolution.
  • Higher signal-to-noise ratios: 5.0-T images had significantly better signal and contrast ratios across all resolutions.
  • No difference in LGE mass: Measurements of LGE mass were similar between the two MRI strengths.

Conclusion

The study concludes that 5.0-T PSIR imaging provides better image quality and LGE visualization than 3.0-T imaging, particularly at a 1.2-mm resolution.
