骨髓核素显像对恶性肿瘤骨髓转移的诊断价值

The diagnostic value of bone marrow scintigraphy in detecting malignant tumor bone marrow metastasis with radionuclide imaging.

目的 :探讨骨髓显像在恶性肿瘤转移中的诊断价值。方法 :选取 82例患者作为研究对象 ,每例患者均在同 1周内接受骨髓显像及骨显像各 1次 ,对发现的病变部位及病变个数进行分析 ,计算其灵敏度。结果 :82例患者 ,其中 32例共发现 369个病灶 ,平均 1 1 5个病灶 ,1 1例患者骨髓显像新发现病灶 2 2个 ,均出现中央骨髓性抑制 ,外周骨髓扩张。 41例发现骨髓中有外来细胞。骨髓显像灵敏度 1 0 0 % ,骨显像灵敏度39 %。结论 :核素骨髓显像的方法是一种无创伤性检查 ,至少可以提前 4个月预报骨转移灶。

Objective:To study the diagnostic value of bone marrow scintigraphy in detecting malignant tumor metastasis.Methods:82 patients with suspected bone marrow metastasis were selected,every patient received bone marrow scintigraphy and conventional bone scan one time respectively within the same week,the lesion regions and quantities were analyzed,the sensibility was calculated.Results:In 32 of 82 patients bone scan found 369 bone metastasis foci,every patient has 11 5 foci on average,11 patients were found to have 22 new bone metastasis foci by bone marrow scintigraphy,all the foci had central arrest of bone marrow and peripheral bone marrow expansion,and 41 patients were found to have extrinsic cells.The sensibility of bone marrow scintigraphy was 100%,the sensibility of conventional bone scan was 39%.Conclusions:The bone marrow scintigraphy is a non invasive examination,it can predict bone metastasis lesions ahead of time at least 4 months
