Abstract:Objective To discuss the history and research progress of MR diffusion tensor imaging(DTI) in the diagnosis of spinal diseases. Methods To analyze and summarize the related literatures about the history and research progress of MR-DTI in the diagnosis of spinal diseases in the database of PubMed, Springer Link and CNKI with the key words of DTI, spinal, spine, etc. Results MR-DTI can reflect not only the early changes of local biological environment, but also the function of water exchange between the tissue components in early spinal cord lesions, it can also track nerve fibers and reflect the integrity of spinal cord. DTI has been gradually applied in the early diagnosis of cervical spondylotic myelopathy, the spinal cord injury period evaluation, the diagnosis of lumber and sacral nerve roots diseases, degeneration of lumber discs, etc. There is a gap between DTI technique and its clinical application in spinal cord lesions due to small volume of spinal cord, long scan time, motion artifacts, etc. With the development of medical imaging technologies, such as parallel imaging and single shot fast spin echo, these problems are being gradually solved. Conclusions DTI has played a significant role in the field of spinal diseases. With the application of more advanced techniques, we can work out solutions for the challenges and problems. DTI will become an unparalleled method in the early diagnosis of spinal diseases.
