Background. Intervertebral disc degeneration (IDD) at the cervicothoracic junction of spine is clinically relevant, however, little attention had been paid. T2 mapping and magnetic transfer ratio (MTR) are useful magnetic resonance imaging (MRI) techniques to quantitatively evaluate IDD, revealing the biochemical changes within the intervertebral disc. To compare T2 mapping with MTR imaging regarding their accuracy to quantitatively diagnose intervertebral disc degeneration at the cervicothoracic junction, influences of anatomical level, gender, age, and Pfirrmann grade of T2 relaxation time values and MTR values were evaluated. Methods. Sixty-seven patients with neck and upper back pain were included and examined with both T2 mapping and MTR imaging. The Pfirrmann grade, T2 relaxation time values, and MTR value of each disc between C7 and T3 were measured. Differences were investigated among different segmental levels, genders, age ranges, and Pfirrmann grades. The diagnostic accuracy of both MRI techniques was compared using the receiver operating characteristic (ROC) curves. Results. No significant difference was detected comparing T2 relaxation time values or MTR values among different anatomical levels, genders, and segmental levels. And we generally found that T2 relaxation time values decreased, while MTR value increased with increasing age. Importantly, we demonstrated the significant correlation between either T2 relaxation time values or MTR value and Pfirrmann grade. Conclusion. We proved the better accuracy of T2 mapping over MTR imaging to quantitatively evaluate the intervertebral disc degeneration of the cervicothoracic junction.

Lumbar Disc Degeneration

During the recent past focus has shifted from identifying intervertebral disc degeneration as being caused by physical exposure and strain to being linked with a variety of genetic variations. The objective of this review is to provide an up to date review of the existing research data regarding the relation of intervertebral disc degeneration to structural protein genes and their polymorphisms and thus help clearly establish further avenues where research into causation and treatment is needed. A comprehensive search using the keywords “Collagen”, “COL”, “Aggrecan”, “AGC”, “IVDD”, “intervertebral disc degeneration”, and “lumbar disc degeneration” from PubMed and Google Scholar, where literature in the English language was selected spanning from 1991 to 2019. There are many genes involved in the production of structural components of an intervertebral disc. The issues in production of these components involve the over-expression or under-expression of their genes, and single nucleotide polymorphisms and variable number of tandem repeats affecting their structures. These structural genes include primarily the collagen and the aggrecan genes. While genetic and environmental factors all come into play with a disease process like disc degeneration, the bulk of research now shows the significantly larger impact of hereditary over exposure. While further research is needed into some of the lesser studied genes linked to IVDD and also the racial variations in genetic makeup, the focus in the near future should be on establishment of genetic testing to identify individuals at greater risk of disease and deliberation regarding the use of gene therapy to prevent disc degeneration.
