核素骨显像与MRI对肿瘤骨转移诊断的对比研究

A comparative study of bone scintigraphy and MRI in diagnosing bone metastases.

目的探讨核素平面骨显像(SPECT)与磁共振成像(MRI)对于诊断肿瘤骨转移的临床价值。方法回顾性分析42例肿瘤患者接受骨显像和磁共振检查的结果。结果42例患者,骨显像阳性35例(83.3%),MRI扫描阳性30例(71.4%),两者比较差异无统计学意义(χ2=1.70,P>0.10)。骨显像阳性病灶数68个,MRI检出病灶数59个,两者比较差异无统计学意义(P>0.10)。骨显像和MRI共检出病灶数127个中,脊柱病灶最多。结论核素平面骨显像仍为筛选肿瘤患者骨转移的首选检查,MRI是其必要的补充手段。

Objective the comparative study value about bone scintigraphy and MRI in evaluating bone metastases, Methods, By restrospectively summarizing 42 patients with malignant tumor received bone scintigraphy and MPd. Results The positive rates of scintigraphy and MRI were 83.3% （35/42） and 71.4% （30/42） （ P 〉 0.10） .68 lesions were found by bone scintigraphy and 59 lesions were detected by MRI （ P 〉 0. 10 ）. Conclusion Compared to MRI, bone scintigraphy may be recommended as the first choice of imaging examination for diagnosis of malignant tumor.
