Cartilaginous Endplate

In order to carry out the evaluation of cartilaginous endplate degeneration based on magnetic resonance imaging (MRI), this paper retrospectively analyzed the MRI data from 120 cases of patients who were diagnosed as lumbar intervertebral disc degeneration and underwent MRI examinations in the designated hospital of this study from June 2018 to June 2020. All cases underwent conventional sagittal and transverse T1WI and T2WI scans, and some cases were added with sagittal fat-suppression T2WI scans; then, the number of degenerative cartilaginous endplates and its ratio to degenerative lumbar intervertebral discs were counted and calculated, and the T1WI and T2WI signal characteristics of each degenerative cartilage endplate and its correlation with cartilaginous endplate degeneration were summarized, compared, and analyzed to evaluate the cartilaginous endplate degeneration by those magnetic resonance information. The study results show that there were 33 cases of cartilaginous endplate degeneration, accounting for 27.50% of all those 120 patients with lumbar intervertebral disc degeneration (54 degenerative endplates in total), including 9 cases with low T1WI and high T2WI signals, 5 cases with high T1WI and low T2WI signals, 12 cases with high and low mixed T1WI and high or mixed T2WI signals, and 4 cases with both low T1WI and T2WI signals. Therefore, MRI scanning can clearly present the abnormal signals of lumbar intervertebral disc and cartilaginous endplate degeneration, accurately identity their lesion locations, and type their degenerative characteristics, which may be best inspection method for the evaluation of cartilaginous endplate degeneration in the early diagnosis of intervertebral disc degeneration. The study results of this paper provide a reference for further researches on the evaluation of cartilaginous endplate degeneration based on magnetic resonance imaging.

Tissue Contrast

Magnetic resonance imaging (MRI) is the most widely used imaging method in clinical lumbar spine examination. Because of its advantages of non-radiation and good tissue contrast, magnetic resonance imaging provides rich and effective diagnostic information for clinic. The most commonly used sequence is type 2 (T2) sequence, which has a longer time (usually longer than 2000 ms). It shows well in long T2 tissues such as nucleus pulposus, cerebrospinal fluid and adipose tissue, showing moderator high signal in images, while for short T2 tissues such as cartilage endplate and anterior and posterior longitudinal zone, it is often no signal and low signal because of its short attenuation time, thus forming obvious tissue contrast. But at the same time, because the time is too long, for short T2 tissue, the signal has been attenuated to zero before sequence acquisition, so the complete structure can not be displayed directly. In this paper, the normal human lumbar intervertebral disc was studied by conventional magnetic resonance type 1 (T1), T2 and double-echo-UTE imaging techniques. Each part of lumbar intervertebral disc and the semi-quantitative analysis of anatomical structure in images were compared, and the advantages and characteristics of each sequence for each anatomical structure of lumbar intervertebral disc and the advantage of MR-UTE in intervertebral disc display were discussed. It has been found that UTE, as a new sequence which can effectively image short T2 tissue, is gradually applied from experiment to clinic in bone and joint system because of its shorter time. In the gross specimens of lumbar intervertebral disc, sequence can directly display the cartilage endplate and the short T2 tissue of the anterior and posterior longitudinal ligament.
