【摘要】：目的:评估单椎体病变的MR表现,提高MR诊断准确性。方法:回顾性分析47例手术及病理证实的单椎体病变的MR表现,分别测量病灶的对比度及强化程度,评价T1W、T2W、T2W脂肪抑制、T1W增强及T1W脂肪抑制增强检查对病变的显示情况,分析病变的MR表现。结果:T2W脂肪抑制及T1W脂肪抑制增强扫描显示病变的对比度较好。其中29例术前诊断正确(61.7%),12例术后分析修正了影像学诊断,6例因影像学表现缺乏特异性而无法做出修正诊断。26例转移瘤中5例术前误诊,21例其他单椎体病变中13例术前误诊。肿瘤性病变不侵犯相邻椎间盘、血管瘤明显强化及黏液的特殊MR表现对于病变的定性有较大帮助。结论:准确把握不同组织的MR表现有助于提高单椎体病变的MR诊断准确性。
[Abstract]:Objective: to evaluate the Mr manifestations of single vertebral lesions and to improve the accuracy of Mr diagnosis. Methods: the MRI findings of 47 cases of surgical and pathologically proved single vertebral lesions were retrospectively analyzed, and the contrast and enhancement of the lesions were measured respectively. To evaluate the enhancement of T1W and T1W of T1W and T1W of T2W, and to evaluate the display of T1W and T1W. Results the contrast of the lesions was better on the enhanced scan of W T 2W fat suppression and T 1W fat suppression, among which 29 cases were diagnosed correctly before operation and 12 cases were diagnosed correctly before and after operation, 6 cases were corrected because of lack of imaging findings. 5 cases misdiagnosed preoperatively in 21 cases of other single vertebral body lesions. 13 cases were misdiagnosed before operation. Tumor lesions did not invade adjacent intervertebral discs. The obvious enhancement of hemangioma and the special Mr manifestations of mucus are helpful to the qualitative analysis of hemangioma. Conclusion: it is helpful to accurately grasp the MRI findings of different tissues to improve the accuracy of Mr diagnosis of single vertebral lesions.
