Abstract: The advantage of noninvasive and whole body imaging makes bone scintigraphy play an important role in the diagnosis of bone diseases, especially in exploring bone metastasis. However, extraosseous uptake on bone scintigraphy has been observed in some instances. Presently, the mechanism of extraosseous uptake is still unclear. Identification of such nonosseous uptake can reduce the blind examinations and improve the diagnostic value of bone scintigraphy. The author reviews the related articles that illustrate the possible causes of extraosseous uptake in the abdominal and pelvic soft tissues to provide essential help for clinical diagnosis.
