目的：比较 MRI与99 Tcm-MDP骨显像在骨转移瘤诊断中的价值。方法对15例骨转移瘤患者分别进行 MRI及99 Tcm-MDP骨显像检查，比较2种方法检出骨转移瘤病变的阳性率。结果15例骨转移瘤中，MRI检查阳性15例，阳性病灶95个，99 Tcm-MDP 骨显像检查阳性13例，阳性病灶61个，MRI 阳性病灶检出率高于99 Tcm-MDP骨显像，差异有统计学意义（χ2＝23．684，P＜0．01）。结论增强T1 WI及 DWI序列的应用，使得 MRI检查较99 Tcm-MDP骨显像具有更高的敏感度和特异度，MRI与核素骨显像二者应互相补充，合理应用于临床。

Objective To compare the diagnosis of MRI and 99 Tcm-MDP bone imaging in bone metastasis.Methods Fifteen patients of diagnosed bone metastatic tumor underwent MRI and 99 Tcm-MDP bone imaging,the positive rate was compared between the two methods.Results MRI showed positive examination in 15 cases,and a total 95 lesions.99 Tcm-MDP bone imaging showed positive examination in 1 3 cases and a total 6 1 lesions.The positive rate of MRI in detection lesions was higher than that of 99 Tcm-MDP bone imaging,the difference had statistical significance(χ2=23.684,P<0.01).Conclusion Post-contrasted T1 WI and DWI made MRI more sensitive than 99 Tcm-MDP bone imaging in examination of bone metastasis.MRI and bone scintigraphy are considered as the complementary diagnostic methods in the detection of bone metastasis.
