“…9,28,29 For the AF T2, our results were similar to those of Stelzeneder et al 28 and Welsch et al, 29 and slightly higher than those of Trattnig et al 9 With respect to the T1 relaxation times, the values encountered for the NP and AF in our study were lower than those found in the literature. 12,[30][31][32] We hypothesize that at least in part, this difference may be due to different magnetic field strengths, because most of the previous studies used 3T MR imaging.…”

“…The most common method in the literature with regard to T1 and T2 is to acquire small regions of interest that are anatomically based. [6][7][8][9] Authors have used standard ROIs, delineating subregions within the intervertebral disk to extract quantitative data specifically from the NP and AF. 6,7 Additional intermediate ROIs on boundaries between the nucleus and annulus have also been used.…”

BACKGROUND AND PURPOSE:Intervertebral disk biochemical composition could be accessed in vivo by T1 and T2 relaxometry. We found no studies in the literature comparing different segmentation methods for data extraction using these techniques. Our aim was to compare different manual segmentation methods used to extract T1 and T2 relaxation times of intervertebral disks from MR imaging. Seven different methods of partial-disk segmentation techniques were compared with whole-disk segmentation as the reference standard.

“…The changes in the biochemical composition during disc degeneration promote a change in T2 relaxation times [11]. T2 maps therefore allow for a quantitative approach to the question of whether different types of disc pathologies can be differentiated via MRI [12][13][14][15]. It is important to notice that T2 values are also dependent on other factors, such as age [16].…”

Purpose Indicating lumbar disc herniation via magnetic resonance imaging (MRI) T2 mapping in the posterior annulus fibrosus (AF). Methods Sagittal T2 maps of 313 lumbar discs of 64 patients with low back pain were acquired at 3.0 Tesla (3T). The discs were rated according to disc herniation and bulging. Region of interest (ROI) analysis was performed on median, sagittal T2 maps. T2 values of the AF, in the most posterior 10% (PAF-10) and 20% of the disc (PAF-20), were compared. Results A significant increase in the T2 values of discs with herniations affecting the imaged area, compared to bulging discs and discs with lateral herniation, was shown in the PAF-10, where no association to the NP was apparent. The PAF-20 exhibited a moderate correlation to the nucleus pulposus (NP). Conclusions High T2 values in the PAF-10 suggest the presence of disc herniation (DH). The results indicate that T2 values in the PAF-20 correspond more to changes in the NP.

The intervertebral disc (IVD) is a joint unique in structure and functions. Lying between adjacent vertebrae, it provides both the primary support and the elasticity required for the spine to move stably. Various aspects of the IVD have long been studied by researchers seeking a better understanding of its dynamics, aging, and subsequent disorders. In this article, we review the surgical anatomy, imaging modalities, and molecular biology of the lumbar IVD. Clin. Anat. 30:251-266, 2017. © 2017 Wiley Periodicals, Inc.

Lumbar intervertebral disc abnormalities: comparison of quantitative T2 mapping with conventional MR at 3.0 T

Abstract: Quantitative T2 mapping of the nucleus pulposus of the intervertebral disc in the lumbar spine at 3 T reveals significant differences in discs with herniation and annular tears compared with discs without these abnormalities.
