Magnetic resonance imaging： a valuable method for diagnosing chronic lumbago caused by lumbar muscle strain and monitoring healingprocess

引用

Chinese Medical Journal 2013年第13期126卷 2465-2471页

作者： OUYANG Lin jia Qian-xin xiao Yu-hui KE Lai-shun HE Ping Department of Medical Imaging People's Liberation Army 175th Hospital Affiliated Southeast Hospital of Xiamen University Zhangzhou Fujian 363000 China

Background Magnetic resonance imaging （MRI） is the most sensitive technique for evaluating the healing process and should be performed before the patients return to their exercise routines. The aim of this research was to diagnose chronic lumbago associated with lumbar muscle strain and to monitor healing process by MRI. Methods Sixty-five symptomatic cases of chronic lumbago caused by lumbar muscle strain were collected from March 2009 to October 2011. MRI was used to examine, diagnose and monitor the healing process. The control group included 65 random cases of asymptomatic volunteers. MRI methods included routine sequences of GRE TlWl, TSE T2WI and special sequences of T2-STIR-FS, combined with DWI. We compared the MRI characteristics of symptomatic cases before and after healing and with asymptomatic controls. Results The important MRI characteristics of chronic lumbago with lumbar muscle strain included：（1） The low back muscle showed edema. （2） The low back intermuscular spaces showed edema and/or fluid. （3） The low back spaces beside the spinous process showed edema and/or fluid. （4） The low back vertebral articular process fossae or transverse process fossae showed fluid. Of these image characteristics, the intermuscular space edema provided the best diagnostic sensitivity, Se=83%, with Y1=0.63, Tr=74%. The low back muscle edema provided the best diagnostic specificity, Sp=100%, with Y1=0.66, Tr=83%. And the spaces edema beside the spinous process provided the best diangnostic accuracy, Tr=86%, with YI = 0.71, Se=80%, Sp=91%. The diagnosis accurate could be improved by combining multiple MRI characteristics. The diagnostic accuracy could achieve n=93%, with Y1=0.86, Se=100% and Sp=86% when two characteristics were combined. After rehabilitation care, the edema disappeared on the repeated MRI. Conclusions MRI may well be a useful diagnostic method for lumbago with lumbar muscle strain. Combining routine sequences with T2-STIR-FS and DWI sequences could demon

"褐"在漫长的语言文字发展过程中,具有表物性,后来出现了表黄黑色彩范畴的义项,表物义项逐渐消失。通过对其他色彩词词义发展轨迹的比对,未来"褐"可能产生更多的义项。"褐"在现代汉语中使用十分广泛,"褐"在一定语境中能独立成词,是拟态色彩词。通过统计语料中"褐"的构词,尚未发现描色词,说明"描色"和"辨色"、"指色"具有继起性。通过"褐"在现代色彩词词群中使用率的对比排序,可以发现色彩词使用频率高低的排序与其出现的先后顺序基本一致。
