MRI和X线在多发骨髓瘤分期诊断中的应用和比较

目的 对照分析多发性骨髓瘤的X线及MRI表现,分析其临床应用价值.方法 对我院2011年至2012年间32例多发性骨髓瘤患者进行X线和MRI检查,并依照影像学检查结果,比较两种方法在Durie/Salmon plus诊断分期中的不同.结果 MRI病灶检出率（27/32,84.37％）明显高于X线检出率（20/32,62.50％）,两组比较差异有统计学意义（P＜0.05）.依照Durie/Salmon plus分期的标准,MRI诊断分期（Ⅰ期5例、Ⅱ期8例、Ⅲ期19例）明显高于X线诊断分期（Ⅰ期12例、Ⅱ期13例、Ⅲ期7例）,差异有显著统计学意义（P＜0.01）.结论 MRI发现多发性骨髓瘤病变的敏感性和特异性均高于X线平片,可为影像诊断提供更可靠的依据.

Comparison of MRI and X-Rays in the Diagnosis of Stage of Multiple Myeloma

Objective To assess the diagnostic value of MRI in patients with multiple myeloma compared with X-rays. Methods 32 patients with multiple myeloma in our hospital from 2011 to 2012 were examined by MRI and X-rays, and the imageological findings were compared according to the Durie/Salmon plus staging system. Results The detection rate of pathological changes was 84.37% （27/32） of MRI, significantly higher than 62.50% （20/32） of X-ray, the difference was statistically significant （P 〈0.05）. According to Durie-Salmon plus staging system, the assessment of MR[ （5 cases of stage I, 8 cases of stage II, and 19 cases of stage IlI） was significantly higher than that of X-rays （12 cases of stage I, 13 cases of stage ]], and 7 cases of stage ]]I ）, and the differences between two groups were statistically significant （P 〈0.0l）. Conclusions As more sensitive and specific, the diagnostic value of MRI is superior to X-rays in patients with multiple myeloma.
