病理证实的90例脊柱肿瘤核素骨显像特点

目的:探讨脊柱肿瘤全身骨平面显像特点及其临床价值.方法和结果:分析90例经手术病理证实的脊柱肿瘤患者99mTc-MDP全身骨平面显像资料.结果表明,49例骨转移瘤中骨显像阳性43例,37例椎体放射性摄取明显增高;30例累及整个椎体,其中18例伴椎体对称性膨大;29例伴有其他骨骼放射性浓聚或稀疏.17例原发恶性骨肿瘤中骨显像阳性12例,11例摄取明显增强,其中8例累及整个椎体,3例为不规则病灶伴不对称性膨出;仅4例伴有其他骨骼病变.24例良性骨肿瘤中骨显像阳性13例,6例摄取明显增高;仅1例伴其他骨骼病变.结论:多脊柱骨转移瘤的骨显像特点是多节椎体放射性异常浓聚或稀疏,多伴有其他部位骨骼病灶,常累及整个椎体,伴对称性膨大.多数原发恶性骨肿瘤表现为单发或多发性脊椎摄取明显增强,多数累及整个椎体,但不伴对称性膨大;少数为局灶性不规则病灶向周围不对称性膨出.

Radionuclide planar bone imaging features of pathologically confirmed spine tumors :an analysis of 90 cases

Objective:To analyze the radionuclide bone imaging features of spine tumors and its clinical value.Methods and results:Data of radionuclide planar whole-body bone imaging with 99m Tc-MDP were analyzed in90patients with various spinal tumors confirmed by histopathology.In49patients with metastases,bone imaging was positive in43;37vertebra showed strong uptake;30patients involved the whole vertebra with symmetrical enlargement in18;other extravertebral bone foci were seen in29.In17patients with primary malignant bone tumors,bone imaging was positive in12;11vertebra showed strong uptake;and8involved the whole vertebra;3focal lesions had local irregular bulging;other extravertebral bone foci were seen in4.In24patients with benign bone tumors,bone imaging was positive in13;6vertebra showed strong uptake; other extravertebral bone foci were seen in1.Conclusion:Spinal metastases in bone imaging are mainly multiple,strong up-take of whole vertebra and accompanied by symmetrical enlargement with other extravertebral bone foci.Primary malignant bone tumor is mainly single or multiple,strong uptake of whole vertebra without symmetrical enlargement,some with local irregular bulging lesions.
