摘要
目的通过对肿瘤骨转移瘤患者分别进行磁共振成像(MRI)和全身核素骨显像(SPECT)并对结果进行比较,探讨两种影像学方法对骨转移瘤诊断效能差异,为临床肿瘤骨转移选择合适的影像诊断方法提供依据。方法对34例经病理证实的恶性肿瘤患者在2周内分别进行SPECT和MRI,对两种检查图像进行双盲法判读,分别记录两种检查图像中骨异常灶的数量及位置,对其检查结果进行分析研究。结果 34例患者中骨显像阳性30例(88.2%),MRI扫描阳性23例(67.6%),两者比较差异具有统计学意义(χ2=4.19,P<0.05)。骨显像显示54个阳性病灶数,MRI显示48个检出病灶数,两者比较差异无统计学意义(P>0.10)。结论核素平面骨显像仍为诊断肿瘤患者骨转移的首选检查,MRI可作为必要的补充检查方式。
Objective Through the comparison of patients who were suspected of bone metastasis received magnetic reso- nance imaging（MRI） and bone seintigraphy respectively ,the investigation of the diagnostic efficacy of MRI and hone scintigraphy for assessment bone metastasis was discussed and the optimal method that diagnose bone metastasis for physicians was provided. Methods 34 patients with malignant tumor confirmed by pathology and checked up by SPECT and MRI within 2 weeks were re- viewed and analyzed. The two methods were interpreted by double blindly and the quantity and location of the abnormal focus of bone in two methods were recorded. Results The positive rates of SPECT and MRI were 88.2% （30/34） and 67.6% （23/34）, P 〈 0.05.54 lesions were found by SPECT and 44 lesions were detected by MRI （ P 〉 0. 10 ）. Conclusion Compare to MRI, SPECT may be recommended as the first choice of imaging examination for diagnosis of bone metastasis of malignant tumor, but MRI was also necessary.
