目的：探讨16层螺旋CT与99Tcm-亚甲基二膦酸盐(99Tcm-MDP)全身骨显像对腰椎骨转移瘤的诊断价值。方法：回顾性分析临床确诊腰椎骨转移瘤且资料完整的住院患者47例63处腰椎骨转移瘤，分析其16层螺旋CT与99Tcm-MDP全身骨显像检查结果。计算两种检查结果的灵敏度及特异度。结果：16层螺旋CT发现43例患者共59处椎体破坏，其灵敏度为84.6%；明确诊断腰椎转移瘤37例，可疑13例；99Tcm-MDP全身骨显像检查发现37例患者共41处椎体放射性异常浓聚，其灵敏度为65.2%，全身骨显像明确诊断腰椎转移瘤27例，可疑9例；39例患者全身骨显像发现椎体外多发放射性异常浓聚。结论：16层螺旋CT对腰椎骨转移瘤的诊断较99Tcm-MDP全身骨显像具有更高的灵敏度，但多数患者经99Tcm-MDP全身骨显像可获得较为明确的诊断。

Objective:To explore the diagnostic value of 16-slice spiral CT and 99Tcm-MDP whole body bone scintigraphy in lumbar spine bone metastases. Methods:The retrospective analysis of 47 cases of hospitalized patients with the clinical diagnosis of lumbar bone metastases and complete information 63 lumbar bone metastases, and analyze the results of 16-slice spiral CT with 99Tcm-MDP whole body bone scintigraphy. Results:We calculated the sensitivity and specificity of the two inspection results. 16-slice spiral CT findings of 43 patients with a total of 59 vertebrae were damaged, sensitivity (84.6%), 16-slice spiral CT clear diagnosis of lumbar metastases in 37 cases, suspicious 13 cases;99Tcm-MDP whole body bone scintigraphy found 37 patientsa total of 41 the abnormal vertebral radioactive concentrated, sensitivity, whole body bone scintigraphy clear diagnosis of lumbar spine metastases in 27 cases, suspicious of nine cases;39 patients with systemic bone scintigraphy found multiple extrapyramidal radioactive anomalies concentrated. Conclusion:16-slice spiral CT diagnosis of lumbar bone metastases compared with 99Tcm-MDP bone scintigraphy has a higher sensitivity, but the majority of patients with a more definitive diagnosis can be obtained by 99Tcm-MDP bone scintigraphy.
