Motion robust high resolution 3D free-breathing pulmonary MRI using dynamic 3D image self-navigator.

Abstract in brief

• The study developed a specialized 3D MRI technique that captures high-resolution images of the lungs during free breathing, using a dynamic self-navigator reconstructed from the imaging data itself to track respiratory motion.
• They used two methods—softgating and motion-resolved techniques—to correct for breathing motion, resulting in clearer images even when scanning during irregular or shallow breathing.
• This approach proved effective in both volunteers and patients, enabling detailed visualization of lung structures and pathologies, with improvements over traditional motion tracking methods.]
