对105例恶性肿瘤患者进行了99mTc－MDP全身ECT骨显像（简称骨显像），其中19例同时进行了X线摄片及CT检查，以比较三者对骨转移瘤的诊断价值。结果显示，骨显像、X线摄片及CT诊断骨转移瘤的敏感度分别为70．5％、52．6％和57．9％，似然比分别为2、39、1．11和1．38。骨显像对胃肠道肿瘤、肺癌、鼻咽癌和乳癌的骨转移瘤敏感度分别为90．9％、77．4％、72．7％和35．7％，似然比分别为9．99、3．43、2．66和0．56。骨转移部位以脊柱和骨盆为多，均为60．8％。提示骨显像适用于骨转移瘤的诊断，其诊断价值高于X钱摄片及CT检查，尤其适用于胃肠道肿瘤、肺癌、鼻咽癌等骨转移瘤的诊断。
99mTc-MDP whole body ECT bone imaging (abbreviated as bone imaging) was performed on 105 patients with malignant tumors. 19 patients underwent X-ray and CT scans simultaneously to compare the diagnostic value of the three bone metastases. The results showed that the sensitivity of bone imaging, X-rays, and CT in the diagnosis of bone metastases were 70.5%, 52.6%, and 57.9%, respectively, and the likelihood ratios were 2, 39, and 1.11, respectively. 1.38. Bone scintigraphy showed sensitivity to 90.9%, 77.4%, 72.7%, and 35.7% of bone metastases in gastrointestinal cancer, lung cancer, nasopharyngeal cancer, and breast cancer, respectively, and the likelihood ratios were 9 .99, 3.43, 2.66, and 0.56. The sites of bone metastases were mostly spine and pelvis, which were 60.8%. Bone scintigraphy is indicated for the diagnosis of bone metastases. Its diagnostic value is higher than that of X-ray and CT scans. It is especially suitable for the diagnosis of gastrointestinal cancers, lung cancers, and nasopharyngeal carcinomas.
