摘　　要：全身骨显像是目前公认的早期诊断骨转移瘤的首选方法，是核医学最常规显像项目之一。然而，骨外组织显影导致的伪影常影响诊断的准确性。对全身骨显像进行评价时，要针对骨外组织显影的各种可能的发生机制（包括药物因素、注射因素、患者因素等）进行综合分析，提高骨显像诊断的准确性。Whole-body bone scintigraphy using ^99Tc^m-methylene diphosphonate, one of the most commonly performed radionuclide examinations, is the first choice for early diagnosis of bone metastases. However, the artifact imaging of the extraosseous tissues invariably affects the accuracy of the diagnosis. It is important to consider all the possible factors of the extraosseous uptake of the imaging agent and aggregate analyse during interpreting the examination.The common causes including the radioactive drug, the injection, the patient-self and so on.
