Overview

This work demonstrates successful free-breathing lung MR Fingerprinting for T1 and T2 mapping, indicating potential clinical implications for pulmonary diseases.

Key Points

  • Free-breathing lung MR Fingerprinting successfully measured T1 and T2 in healthy subjects, showing feasibility for clinical use.
  • Average T1 values were 645±123ms during inspiration and 638±129ms during expiration, while T2 values were 42±2ms and 44±2ms respectively.
  • Data was collected using a 30-second free-breathing MRF sequence at 0.55T with respiratory self-navigation for improved accuracy.
  • Highlights the potential for monitoring pulmonary diseases, such as emphysema and COPD, through advanced imaging techniques.
