磁共振评价躯体病变的定位研究与应用

背景：以往的医学影像检查手段只限于检查病变,对病变影像定位、定性等,而不能做到直观表面定位,为了更好的帮助临床准确定位就需要一种装置,在检查病变同时做到准确定位。目的：分析磁共振检查躯体骨骼及软组织病变定位器准确性。方法：检索磁共振检查躯体骨骼及软组织病变的定位研究与应用的相关研究文献,检索词为＂磁共振（magnetic resonance imaging,MRI）,定位（location）,诊断（diagnosis）,躯体病变（bodylesions）,占位性病变（space-occupying lesions）,定位器（locator）,神经系统疾病（nervous system disease）,神经外科（neurosurgery）＂,语言分别设定为中文和英文。结果与结论：磁共振扫描前将定位器固定于可疑病变部位,透过该定位器进行扫描,扫描完成后做好表面定位,患者在定位下分别实施穿刺、手术、放疗。使用磁共振检查躯体病变定位器均能快速定位,准确性高,且能避开大血管、神经及韧带等重要功能区;对手术或穿刺治疗起到重要指导作用。磁共振检查肢体病变定位器操作简单、使用灵活,固定方便、使用安全,结构合理,技术创新,能确定病变的精确空间位置,克服了手术中寻找病灶难的问题,有利于查找微小的病变,或者是在某个序列不能很好显示的病变。

Application of magnetic resonance imaging in the location of the body lesions

BACKGROUND：Medical imaging means has confined to the lesion,and could not locate the lesion intuitively for the image positioning,qualitative.A positioning equipment needs to be made in order to better help clinicians to accurately locate in the lesion. OBJECTIVE：To investigate body bone and soft tissue lesions positioning methods,analysis of the accuracy of MRI body bone and soft tissue lesions locator.METHODS：A computer online retrieval was performed to search papers regarding the application of magnetic resonance imaging in the location of the body lesions,using key words of ＂magnetic resonance imaging,location,diagnosis,body lesions,space-occupying lesions,locator,nervous system disease,neurosurgery＂ in both Chinese and English. RESULTS AND CONCLUSION：MRI scans is fixed to the suspected lesion.A good surface positioning has been done after the scan is complete,and implementation puncture,surgery,radiotherapy.The body lesions locator can quickly locate high accuracy,and avoid the important functional areas of the large blood vessels,nerves,and ligaments.Body bone and soft tissue lesions play an important role in guiding surgery or puncture treatment.MRI body bone and soft tissue lesions locator in the examination of body space-occupying lesions is characterized by accurate positioning,diagnosis and treatment of the lesion.The operation of MRI lesions locator is simple and flexible,convenient and safe to use,reasonable structure,technological innovation,which can determine the precise spatial location of the lesions,and overcome the problem of lesions difficult surgery,finding tiny lesions in a sequence.
