Recognizing the different mechanisms and imaging appearance of extraskeletal Tc-99m methylene diphosphonate uptake enhances the diagnostic value of bone scan interpretation. In this article, we present a pictorial review of the different mechanisms of extraskeletal Tc-99m methylene diphosphonate uptake on bone scintigraphy including neoplastic, inflammatory, ischemic, traumatic, excretory, and iatrogenic. We also illustrate through case examples the added value of correlation with cross-sectional and single photon emission computed tomography and computed tomography imaging in localizing and characterizing challenging cases of extraskeletal uptake.
认识到骨外锝-99m亚甲基二膦酸盐摄取的不同机制和影像表现可提高骨扫描解读的诊断价值。在本文中，我们对骨闪烁显像中骨外锝-99m亚甲基二膦酸盐摄取的不同机制进行了图谱综述，包括肿瘤性、炎症性、缺血性、创伤性、排泄性和医源性。我们还通过病例示例说明了与横断面和单光子发射计算机断层扫描及计算机断层扫描成像相结合在定位和鉴别具有挑战性的骨外摄取病例方面的附加价值。
