An application of parallel imaging and deep-learning reconstructed T2 mapping in nasal cartilage

Rhinoplasty is a reversible surgery; MRI became a non-invasive post-surgery tracking approach to assess the influence of implant-compressed on nasal cartilage such as mechanical stress, cellular organization and tissue degeneration, etc. Widely-used T2 mapping in musculoskeletal imaging such as knee, shoulder and pelvics takes long acquisition time and thus deters clinical utility. With greater number of multi-channel coils and parallel imaging techniques, scan time shortens but noise enhances. With the additional deep-learning reconstruction, T2 mapping with parallel imaging was stable with small RMS CV% = 0.077% to parallel imaging only image data sets.
