A portable Halbach-based MRI system at 90 mT was used for in-vivo zero-echo-time (PETRA) imaging and variable-flip-angle T1 mapping, revealing short-T2 hard tissues such as ligaments, tendons, cartilage, and bone.
T1 Mapping using variable flip angle SPGR data with flip angle correction,

Qualitative and quantitative hard-tissue MRI with portable Halbach scanners
A portable Halbach-based MRI system at 90 mT was used for in-vivo zero-echo-time (PETRA) imaging and variable-flip-angle T1 mapping, revealing short-T2 hard tissues such as ligaments, tendons, cartilage, and bone.
