"T1 C+ (Gd): post-contrast enhancement of bone marrow, abscess margins, periosteum, and adjacent soft tissue collections"
"Although an organism is cultured from tissue sampling in ~35% (range 21-50%) of cases 11,18, when one is isolated, Staphylococcus aureus is by far the most common pathogen. Different organisms are more common in specific clinical scenarios 1,3,18:"
"Staphylococcus aureus: 80-90% of all infections; includes MRSA"
"Pseudomonas spp.: intravenous drug use and genitourinary tract infection"
"Klebsiella spp.: intravenous drug use and genitourinary tract infection"
"Haemophilus influenzae: neonates (now uncommon in areas with high vaccination coverage 22)"

"vertebrae: lumbar > thoracic > cervical; most common site of haematogenous osteomyelitis in adults, with an increasing incidence with age 23"
"inability to confidently detect marrow oedema; therefore, a normal CT does not exclude early osteomyelitis"
"diabetic osteomyelitis, especially combined with Tc-99m-phosphonate imaging 6; however, MRI is now generally used in conjunction with plain films 13"
"It does, however, have a role in the assessment of soft tissues and joints adjacent to infected bone, as it can be used to visualise soft tissue abscesses, cellulitis, subperiosteal collections, and joint effusion 2."
