"Cortical bone contains Haversian systems (osteons) which contain a central Haversian canal surrounded by osseous tissue in a concentric lamellar pattern. The Haversian canals contain vessels which supply blood to the cellular elements of the osteon (e.g. osteoblasts, osteocytes, and osteoclasts)."
"The outermost layer of cortex contains few mobile protons. The result is low signal (black) on all pulse sequences, except those with ultrashort-TE 4. The periosteum is normally not visible with MR, but periosteal reactions may be detected sooner than with radiographs."
