摘要
目的:分析MRI与CT在老年胸腰椎压缩性骨折诊断中的应用.方法:选取 2019 年7 月—2021 年7 月建昌县人民医院收治的 78例老年胸腰椎压缩性骨折患者为研究对象,并随机将其分为对照组和观察组,各 39 例.所有患者均先进行X线检查,对照组采用CT进行诊断,观察组采用MRI进行诊断,对比 2 组的诊断结果.结果:以X线检查结果为标准,观察组准确度为97.44%,高于对照组的 79.49%,差异有统计学意义(P＜0.05).陈旧骨折椎体的加权图像表现为T1 高信号、T2 等信号、抑脂T2长低信号;形态表现为扁平、楔形;椎体周围软组织均无异常信号.新鲜骨折椎体的加权图像表现为T1 低信号(不规则)、T2高信号、抑脂T2高信号;形态表现为扁平、楔形、凹陷形;椎体周围软组织均存在异常信号分布.结论:使用MRI对老年胸腰椎压缩性骨折患者进行检查较CT检查更加全面,准确度更高,能够明确骨折新旧程度,为临床诊断提供更加准确的影像资料.
Abstract
Objective:To analyze the application of MRI and CT in the diagnosis of compression fractures of thoracolumbar verte-brae in the elderly patients.Methods:78 elderly patients with diagnosis of compression fractures of thoracolumbar vertebrae admitted to Jianchang County People's Hospital from July 2019 to July 2021 were selected as the study objects and randomly divided into a control group and an observation group,with 39 cases in each group.The control group was diagnosed by CT,the observation group was diag-nosed by MRI,and the diagnostic results of the two groups were compared.Results:According to the results of X-ray examination,the accuracy of the observation group was 97.44%,which was higher than 79.49% of the control group,and the difference was statistically significant(P<0.05).The weighted images of old fractured vertebra showed T1 high signal,T2 equal signal and anti fat T2 long low sig-nal;the morphology is flat,wedge-shaped;there were no abnormal signals in the soft tissues around the vertebral body.The weighted images of newly fractured vertebra showed low T1 signal(irregular),high T2 signal and anti fat high T2 signal;the morphology is flat,wedge-shaped and concave;the abnormal signal distribution was found in the soft tissues around the vertebral body.Conclusion:MRI is more comprehensive,and it has higher accuracy than CT in the examination of elderly patients with diagnosis of compression fractures of thoracolumbar vertebrae,which can identify the old and new degree of fractures and provide more accurate image data for clinical di-agnosis.
