Overview

Analysis shows enhanced pulmonary imaging in healthy volunteers, suggesting applications in respiratory diagnostics.

Key Points

  • Excellent pulmonary vessel delineation was achieved, indicating strong imaging capability.
  • No significant differences in sharpness or apparent SNR were found at different spatial resolutions during the imaging.
  • A bSSFP-UTE sequence was utilized to obtain high-resolution images under free-breathing conditions.
  • This validation supports clinical translation of low-field UTE lung imaging techniques for better respiratory assessments.
