摘　　要：目的探讨肺肿瘤患者核素骨显像时肺部软组织病灶异常摄取的临床意义并与X线、CT等相关影像学检查进行对比分析。方法静脉注射^99m/TC-亚甲基二膦酸盐（MDP）555—925MBq，静脉注射后3—6h进行检查，使用Elscint APEX-6型单光子发射计算机断层扫描机进行全身骨显像，必要时增加局部静态显像。所获得图像，根据病变处软组织和骨骼放射性浓聚或减低情况，并结合X线、CT扫描结果进行判断、分析。结果本组15例肺肿瘤患者均肺部软组织异位摄取。其中团块状浓聚12例、片状浓聚2例、结节状浓聚1例。其中尚有8例同时伴有骨转移。结论核素骨显像时，肺部软组织异常摄取骨显像剂多提示为恶性肿瘤，应结合X线、CT等相关影像学检查综合分析。Objective To evaluate the clinical significance of pulmonary abnormal soft tissue uptake of the patients with lung neoplasms by using radionuclide bone imaging, and to contrast the findings with related images such as X-ray and computed tomography. Methods Whole body bone seannings were taken by SPECT of Elseint APEX-6 3-6 hours later after ^99mTe-methylene diphosphonie acid （MDP） 555-925 MBq was injected. Regional static imagings were additionally taken if necessary. The images were analysed according to the hot or cold imagings of the soft tissue and bone lesion, and were contrasted with X-ray and CT images. Results Fifteen eases of lung neoplasms had abnormal pulmonary soft tissue uptake. Among them, 12 eases showed agglomerate imaging,2 sheet imaging and 1 nodal imaging. Eight eases accompanied with bone metastases. Conclusion Abnormal pulmonary soft tissue uptake by using radionuclide imaging often indicates malignant tumor,but the analysis should be combined with related findings such as X-ray and computed tomography.
