摘　　要：目的探索全身骨显像中异常骨外摄取的原因及意义。方法回顾性分析43例在行全身骨显像中出现骨骼以外异常摄取组织影像的患者,并与病理、影像结果及随访对照,分析骨骼外组织摄取临床意义。结果在43例骨外软组织摄取中,其中有28例经病理或随访证实为恶性病灶(65.1%);异常骨外摄取部位主要集中在胸(48.8%)、腹部(39.5%)。肺、肝、乳腺为胸腹部显影摄取的主要器官,且多为原发或继发性恶性肿瘤。结论在排除生理性摄取及技术因素引起的骨外软组织摄取后,异常脏器结节状及弥漫性摄取都具有不同的临床意义,主要见于原发及继发性恶性病变。Objective To explore the clinical significance and main reason of abnormal uptake in extraskeletal soft tissue.Methods A total of 43 cases with extroskeletally activity were retrospectively analysed in whole body bone imaging.For the sake of summing up clinical significance,we compared imaging results with pathology,other imaging,follow-up visited and analysed its reason.Results With abnormal uptake of 43 cases,28cases（65.1%）were confirmed malignant tumors that focused in chest（48.8%）and abdomen（39.5%）,particularly on lung,live,breast.These lesions were usually primary and secondary malignant tumor.Conclusion By excluding physiological or technical factor uptake,the abnormal uptake of the soft tissue and organ prompt primary and secondary malignant tumors which provide more valuable guidance information.
