The Application and Forensic Significance of Imaging Examination in Lumbar Intervertebral Disc Herniation after Injury

Abstract

X-ray and CT are commonly used in post-traumatic examination of bone joints, spine, etc, as a traditional imaging examination method. It is a correct and meaningful method and procedure to observe signs and measurement data by imaging examination, in the cases of traumatic lumbar injuries which need forensic identification. What is the first that spring to our mind is the simple, economical, and practical X-ray examinations, as well as the CT examinations that have unique advantages for bone changes in all traditional and conventional imaging techniques before the performing imaging studies. The changes of the morphological, is also reflected on the changes of MR signal intensity. The distance of the lumbar MR disc more than the median sagittal line, the degree of spinal stenosis etc, as a quantifiable data, can be used to improve the detection of this disease. On this basis, MR has become the first imaging examination method what we need to consider. MRI not only has characteristic imaging performance, but also has rich observation indicators and projects. It can be further used to identify the new injury or old wounds of lumbar disc herniation on the basis of image signs by quantitative and qualitative aspects. MR examination method is regarded as an important means of inspection in the forensic identification of this disease.
