摘要
目的旨在探讨多序列MRI扫描在诊断腰椎压缩性骨折中的临床应用价值。方法选取我院2018年2月-2018年8月收治的腰椎压缩性骨折患者51例,患者均进行了MRI检查,进行常规快速自旋回波序列、快速自旋回波序列、脂肪抑制序列扫描,收集患者临床资料及影像学资料,由主治医师分析总结51例腰椎压缩性骨折患者不同MRI扫描序列的图像表现,分析多序列MRI扫描在腰椎压缩性骨折中的临床应用价值。结果 51例患者共66个椎体出现凹陷形或扁平形改变,椎体压缩程度:压缩<1/3的椎体36个,压缩1/3-1/2的椎体21个,压缩>1/2的椎体9个。66个椎体后缘骨皮质在MRI图像中主要表现为骨皮质后缘上、下角后翘,后缘皮质则呈现成角改变,受压缩椎体为不均匀长T1信号,椎体内信号特征:T1WI扫描呈现低信号,T2WI扫描呈中等或稍高信号,脂肪抑制STIR序列多数患者椎体内呈现不规则高信号,椎弓根受累,同时可伴异常骨碎片及椎间盘影,16个椎旁软组织出现水肿、血肿。与手术结果对照,多序列MRI扫描检查对51例腰椎体压缩性骨折患者诊断正确率为100%(51/51)。结论多序列MRI扫描诊断腰椎压缩性骨折正确率高,可有效显示腰椎压缩性骨折的不同特征性征象,为临床提供可靠的影像学资料。
Objective To explore the clinical application value of multi-sequence MRI scanning in the diagnosis of lumbar compressive fracture. Methods A total of 51 patients with lumbar compressive fracture admitted to our hospital from February 2018 to August2018 were selected. All the patients underwent MRI examination and were scanned with conventional rapid spin echo sequence, rapid spin echo sequence and fat inhibition sequence. Clinical data and imaging data of the patients were collected, and the images of 51 patients with lumbar compressibility fracture were analyzed and summarized by two physicians, and the clinical application value of multiple MRI scans in lumbar compressibility fracture were analyzed. Results A total of 66 vertebral bodies were found to be depressed or flattened in the 51 patients. The compression degree of vertebral bodies was: 36 vertebral bodies were compressed less than 1/3, 21 vertebral bodies were compressed from 1/3 to 1/2, and 9 vertebral bodies were compressed more than 1/2. 66 vertebral rear bone cortex in MRI image mainly for bone cortex on the trailing edge,the Angle become warped, after trailing the cortex are Angle change, the compression vertebral body for the uneven long T1 signal, vertebral body signal characteristics: low signal in T1 WI scanning sequence, middle or slightly high signal on T2 WI imaging, fat suppression STIR sequence demonstrated irregular high signal, the majority of patients with vertebral body pedicle also show high signal, at the same time with abnormal bone fragments and the intervertebral disc, 16 vertebral there near soft tissue swelling, hematoma signal change. In comparison with the results of surgery, the diagnostic accuracy of multiple MRI scans was 100%(51/51) for 51 patients with lumbar compressive fracture.Conclusion Multi-sequence MRI scanning has high accuracy in diagnosing lumbar compressibility fracture, which can effectively show different characteristic features of lumbar compressibility fracture and provide relevant reliable image data for clinic.
