Bone scintigrams are usually obtained for evaluation of skeletal abnormalities; soft-tissue abnormalities are often an unexpected finding. However, the recognition of specific conditions with extraskeletal accumulation of bone-seeking radiopharmaceuticals greatly enhances the diagnostic value of the study. Several examples of abnormal nonosseous uptake in both neoplastic and nonneoplastic processes involving the brain, lung, heart, breast, bowel, liver, spleen, skeletal muscle, kidney, and bladder are presented. Examples of artifactual uptake in the soft tissues are also described. Causes for nonosseous accumulation are discussed.
骨闪烁扫描通常用于评估骨骼异常；软组织异常往往是意外发现。然而，认识到骨摄取放射性药物在骨骼外积聚的特定情况，可大大提高该检查的诊断价值。本文介绍了涉及脑、肺、心、乳腺、肠、肝、脾、骨骼肌、肾和膀胱的肿瘤性和非肿瘤性过程中异常非骨摄取的几个例子。还描述了软组织中伪影摄取的例子。并讨论了非骨积聚的原因。
