放射性核素骨扫描与MRI诊断恶性肿瘤骨转移的对比研究(附53例报道)

Comparative Study of Radionuclide Bone Scans and Magnetic Resonance Imaging in Diagnosis of Malignant Bone Metastasis

目的探讨放射性核素骨扫描与MRI在诊断恶性肿瘤骨转移方面的比较。方法回顾性分析山西阳泉市第一人民医院2008年7月至2009年3月收治的53例恶性肿瘤患者的放射性核素骨扫描中的单光子发射计算机体层成像术(SPECT)(平面+体层)和MRI资料,按颈椎、胸椎、腰椎、骨盆、肋骨、胸骨、四肢骨7个区域,记录骨转移情况。比较骨扫描和MRI的结果。结果转移发生部位以胸椎、腰椎、骨盆、胸骨、肋骨为主。其中有41位患者189个区域确定为骨转移的,骨扫描平面发现136个区域,骨扫面体层显示又发现35个区域。总计171个区域,占90.4%。MRI发现158个区域,占83.5%。骨扫描主要发现成骨性病变共占165个,6个溶骨性病变;MRI发现24个溶骨性病变,134个成骨性病变。结论 MRI与放射性核素骨扫描在诊断恶性肿瘤骨转移上有互补性,联合检查可以提高骨转移的检出率。

Objective The aim of this retrospective study was to compare the nuclide bone scan and MRI in detecting bone metastasis in various cancers.Methods Fifty-three cancer patients who had nuclide bone scan and MRI were included.The diagnosis of bone metastasis based on the detecting results of nuclide bone scan and MRI was compared and analyzed.Results Forty-one patients with 189 regions were diagnosed have bone metastasis,nuclide bone scan had founded 171 regions and MRI founded 158 regions.Nuclide bone scan founded the mostly ossities and MRI founded the mostly osteolysis.Conclusions It is worth noting the difference of nuclide bone scan and MRI in evaluating bone metastasis and the combined performance.Undoubtedly,the combination of nuclide nuclide bone scan and MRI provide a higher value in bone metastasis diagnosis.
