Bone scanning, which can be used in the assessment of JIA, is characterized as follows:

  • This modality can be used when physical findings do not document definite arthritis.

  • It can also be used to identify a potential focus of osteomyelitis, osteoid osteoma or other abnormality.

  • Bone scanning is characterized by high sensitivity and low specificity

  • It may be combined with single-photon emission CT (SPECT) scanning to increase sensitivity in the 1 or more foci of abnormal isotopic accumulation.

  • Bone scintigraphy is primarily used in the determination of the distribution of JIA, but the substantial radiation dose from this modality is a major disadvantage
