On MRI, susceptibility artifact limits regional visualization and directly correlates with magnetic field strength. Basic metal artifact reduction can be performed by increasing bandwidth, decreasing slice thickness, increasing echo train length, and increasing matrix size [20]. Advanced MR software packages and sequences have been developed for more robust through-section and in-plane artifact reduction. Osteomyelitis commonly occurs in young children, with half of cases reportedly in children <5 years of age [13,21]. Although hematogenous bacterial seeding is the most common underlying cause for osteomyelitis, a history of trauma, often minor, is frequently elicited [11,13]. Infants and toddlers with septic arthritis or osteomyelitis often present with a limp, though it is often difficult in this population to localize a site of involvement on physical examination. In these cases, imaging is often utilized to help identify the affected site [22]. Concurrent osteomyelitis and septic arthritis are common. 3-Phase Bone Scan Area of Interest There is no relevant literature regarding the use of 3-phase bone scan of the area of interest in the initial evaluation of osteomyelitis or septic arthritis in children <5 years of age. Osteomyelitis or Septic Arthritis-Child Bone Scan Whole Body There is no relevant literature regarding the use of whole-body bone scan in the initial evaluation of osteomyelitis or septic arthritis in children <5 years of age. Bone Scan Whole Body and 3-Phase Bone Scan Area of Interest There is no relevant literature regarding the use of whole-body bone scan with 3-phase bone scan of the area of interest in the initial evaluation of osteomyelitis or septic arthritis in children <5 years of age. CT Area of Interest There is no relevant literature regarding the use of CT in the initial evaluation of osteomyelitis or septic arthritis in children <5 years of age.
