摘 要:目的分析和探讨脊柱转移瘤在核磁共振(Magnetic resonance imaging,MRI)常规序列的特征表现以及其诊断价值。方法回顾性分析我院脊柱病区2011年1月~2014年2月的符合病例收集纳入标准113份病例。其中脊柱转移瘤组有42例,非脊柱转移瘤组有71例。平均年龄(63±13)岁。对所有病例的年龄、性别、症状、体征、病史及初次检查MRI特征进行诊断脊柱转移瘤灵敏度和特异度分析。结果发病年龄、性别和神经障碍的组间差异无明显统计学意义。肿瘤病史和发热在组间的差距具有统计学意。具有统计学意义的MRI特征差异有病变累及颈椎(28.6%,93%)、椎旁肿物(57.1%,94.4%)、脊椎附件破坏(73.8%,83.1%)、STIR序列病变累及椎体后部(61.9%,85.9%)。结论在引起脊柱病变的多种疾病诊断中,MRI的应用是至关重要的,特征差异有病变累及颈椎、椎旁肿物、脊椎附件破坏、STIR序列病变累及椎体后部是具有诊断意义的特征标志。通过脊柱转移瘤在MRI常规序列上的特征来诊断脊柱转移瘤具有重要意义。Objective To assess the cheracteristics of spinal metastases on conventional MRI and their diagnosis values.Methods MRI features data of 113 cases including spinal metastases(42 cases) and non- spinal metastases group(71cases) with pathologically and clinically proven from January, 2011 to February 2014 were retrospectively analyzed.The average age was(63±13) years old. Results There was no statistic disparity in terms of genders, but in terms of fever and past related history. The useful MR imaging features with sensitivity and specificity were: involvement of cervical vertebras(28.6%, 93%), paravertebral neoplasm(57.1%, 94.4%), accessories disruption(73.8%, 83.1%)and involvement of posterior vertebras(61.9%, 85.9%). Conclusion MRI examination is significant for spinal pathological changes diagnosis, the MRI features of spinal metastases are crucial in diagnosis.
