目的探讨核素骨显像在肿瘤骨转移随访中的临床价值。方法对97例肿瘤患者静脉注射99TcmMDP925MBq～1 110MBq行271人次SPECT全身骨显像,观察转移瘤在全身骨骼的放射性分布情况并对结果分析。结果在接受2～9次骨显像随访的恶性肿瘤患者中,最终发现49例骨转移瘤,占50.5%。第1、2、3次被确诊为骨转移瘤分别为23例(23.7%);16例(16.5%);7例(7.2%);第4～6次被确诊骨转移瘤各有1例(1.03%)。结论肿瘤病人核素骨显像的定期随访,对骨转移的早期发现、治疗方案的选择、治疗效果的评估有重要意义。
Objective To investigate the clinical value of radionuclide bone imaging in the follow-up of tumor metastasis. Methods 97 patients with tumor were intravenously injected with 99TcmMDP925MBq ~ 1 110MBq line of 271 SPECT whole body bone scintigraphy to observe the metastatic tumor in the bones of the radioactive distribution and analysis of the results. Results Of the patients with malignant tumors followed up from 2 to 9 years, 49 cases of bone metastases were found, accounting for 50.5%. 23 cases (23.7%) were diagnosed as bone metastases in the first, second and third times respectively; 16 cases (16.5%) and 7 cases (7.2%); the fourth to sixth diagnosed bone metastases each had 1 case (1.03%). Conclusion The regular follow-up of radionuclide bone imaging in cancer patients is of great significance for the early detection of bone metastases, the choice of treatment options and the evaluation of the therapeutic effect.
