Data are presented as median (IQR) unless stated otherwise.
↵† Data were available for only 44 patients on height and weight, and for 41 patients on duration of disease.
↵‡ Other 4 patients had recurrent fever (1), juvenile idiopathic arthritis (1), and unknown conditions (2) at the time of MRI.
↵§ Basic WB-MRI protocol includes STIR sequence of coronal plane of entire body (upper extremities excluded) in 4–5 stations, and sagittal plane of entire spine in 2 stations.
↵¶ Complete WB-MRI protocol added STIR sequence of axial plane of pelvis and knees, coronal plane of upper extremities, as well as sagittal plane of ankles to the basic WB-MRI protocol. CNO: chronic nonbacterial osteomyelitis; IQR: interquartile range; WB: whole body; MRI: magnetic resonance imaging; STIR: short-tau inversion recovery.
