[目的]探讨核素骨显像对消化道肿瘤骨转移的临床诊断价值。[方法]分析605例消化道肿瘤患者中骨转移患者的全身骨显像结果。[结果]605例肿瘤患者中,297例(49.09%)发生骨转移。多发骨转移(88.22%)多于单发骨转移(11.78%)。转移灶的分布多为邻近转移,且躯干骨多于四肢骨和颅骨。69.36%患者有骨痛症状。[结论]核素骨显像对消化道肿瘤骨转移诊断具有诊断价值。消化道肿瘤患者在随访中应常规行核素骨显像。
[Objective] To investigate the clinical value of radionuclide bone imaging in diagnosis of bone metastasis of digestive tract tumors. [Method] To analyze the results of whole body bone imaging in patients with bone metastasis in 605 cases of gastrointestinal cancer. [Results] Of the 605 tumor patients, 297 (49.09%) had bone metastases. Multiple bone metastases (88.22%) than single bone metastases (11.78%). The distribution of metastases are mostly adjacent to the transfer, and trunk more than the limbs and skull bone. 69.36% patients had bone pain symptoms. [Conclusion] Radionuclide bone imaging is of diagnostic value in the diagnosis of digestive tract tumor bone metastasis. Patients with gastrointestinal cancer at follow-up should be routine nuclide bone imaging.
