Overview

This technique achieves rapid lung T2* quantification, enabling improved assessment of lung diseases.

Key Points

  • The new method allows for effective lung T2* quantification within a single 15-second breath-hold, enhancing patient comfort and throughput.
  • Results indicate a reduced echo interval of 0.57 ms and a spatial resolution of 2 mm, improving accuracy in lung imaging.
  • Applying a radial-spiral hybrid trajectory enables efficient acquisition of multiple echoes, increasing scan efficiency.
  • This technique highlights the potential for quick and precise lung T2* assessments to evaluate structural and functional lung changes.
