“…For zygapophyseal osteoarthritis, both the intra- and inter-rater reliability estimates were better than previously reported [ 11 ], which is most likely explained by the use of a dichotomous variable in the current study compared to a classification with four severity categories [ 11 ].…”

“…Another limitation is the involvement of only reader A in the intra-rater analysis. Two considerations explain this: 1) previous reliability studies found higher [ 7 – 9 , 12 , 14 , 21 ] or similar/higher [ 10 , 11 , 13 ] intra-rater reliability than inter-rater reliability and 2) involvement of reader A was necessary since a future prognostic study will involve MRI assessments performed by reader A. As for the inter-rater reliability, the study included three readers, only one of these being a radiologist.…”

“…Previous reliability studies on cervical spine MRI have found moderate to almost perfect inter-rater reliability in the assessments of disc-related parameters (kappa (Κ) 0.44[ 7 ], Κ 0.43–0.65 [ 8 ] and Κ 0.73–0.83 [ 9 ]). Almost perfect reliability has been reported for assessments of neural foraminal stenosis (Κ > 0.9 [ 10 ]), fair reliability for facet joint arthrosis (Κ 0.23–0.38 [ 11 ]), and moderate to substantial reliability for spinal canal stenosis (Κ 0.55–0.72 [ 11 ]). Most studies have focused on only one or a few degenerative variables [ 7 – 13 ] and compared readers with similar educational backgrounds and levels of experience [ 7 – 10 , 12 – 14 ].…”

BackgroundKnowledge about the assessment reliability of common cervical spine changes is a prerequisite for precise and consistent communication about Magnetic Resonance Imaging (MRI) findings. The purpose of this study was to determine the inter- and intra-rater reliability of degenerative findings when assessing cervical spine MRI.MethodsFifty cervical spine MRIs from subjects with neck pain were used. A radiologist, a chiropractor and a second-year resident of rheumatology independently assessed kyphosis, disc height, disc contour, vertebral endplate signal changes, spinal canal stenosis, neural foraminal stenosis, and osteoarthritis of the uncovertebral and zygapophyseal joints. An evaluation manual was composed containing classifications and illustrative examples, and ten of the MRIs were evaluated twice followed by consensus meetings to refine the classifications. Next, the three readers independently assessed the full sample. Reliability measures were reported using prevalence estimates and unweighted kappa (Κ) statistics.ResultsThe overall inter-rater reliability was substantial (Κ ≥ 0.61) for the majority of variables and moderate only for zygapophyseal osteoarthritis (Κ = 0.56). Intra-rater reliability estimates were higher for all findings.ConclusionsThe present classifications for some of the most common cervical degenerative findings yielded mainly substantial inter-rater reliability estimates and substantial to almost perfect intra-rater reliability estimates. .Trial registrationRegional Data Protection Agency (J.no. 1–16–02-86-16).

“…Magnetic resonance imaging (MRI) is a useful modality in the assessment of IVDD, since it is highly sensitive to the water content within the tissue [ 3 ]. T2-weighted (T2-WI) and T1-weighted (T1-WI) MRI are the most common techniques to examine the health of intervertebral discs.…”

Aims To investigate the correlation between the apparent diffusion coefficient (ADC) value and cervical intervertebral disc degeneration in adult symptomatic patients. Methods A total of 52 symptomatic and 40 healthy volunteers were included. DWI and routine MRI examinations were performed to their cervical spines. The cervical discs (from C2-C3 to C6-C7) were graded according to the Pfirrmann grading system, and ADC values of the nucleus pulposus (NP) were measured. Differences of the ADC values between different genders and anatomic levels were analyzed; the correlation between the ADC value and the Pfirrmann grade was investigated. The cut-off ADC values of each Pfirrmann grade were calculated. Results The mean ADC value of the NP decreased with increasing Pfirrmann grade (I–V) upon both patients and asymptotic volunteers. The ADC value decreased descendingly from C2-C3 to C5-C6 (P < 0.05) and then increased at C6-C7 (P < 0.05). Additionally, the comparison of the ADC values between different genders achieved statistical significance at each anatomical level (P < 0.05), except at C6-C7 (P > 0.05). Significant negative correlations between the ADC value and either age or Pfirrmann grade were observed. Conclusions Our preliminary findings suggest that the ADC value obtained by DWI can provide a reliable indicator to evaluate the cervical disc degeneration.

“…In this study, we chose multislice CT imaging to examine degenerative changes of the cervical spine. Because reformatted CT images of the spine with bone algorithms is excellent to demonstrate degenerative changes such as reduced height of the intervertebral space, osteophytes, sclerosis of the adjacent cartilaginous endplates, facet joint arthrosis, calcifications and narrowing of the spinal canal [18,19]. Although the grading system for the cervical facet joint arthrosis on CT images were defined in the literature before, in this study we could not find a appropriate grading and scoring system for tomography to compare findings of disc degeneration in both groups.…”

Objective: Recently few studies have described presence of cervical spine anomalies in obstructive sleep apnoea syndrome (OSAS) patients. It is also reported that some cases of cervical spine pathologies and osteophytes producing obstructive sleep apnea. We aim to investigate the prevalence of facet joint arthrosis and degenerative disc disease (DDD) in cervical spine using computed tomography (CT) in OSAS patients. Materials and Methods:We studied on thirty patients with OSAS who had cervical spine CT. Facet joints were evaluated in four grades and scored in 1-4 points by using multiplanar CT images. Disc levels was evaluated by using two-point subjective scale for loss of height, posterior osteophytes, endplate sclerosis, and spinal canal stenosis to determinate DDD. Degeneration of anterior atlanto-odontoid joint (AAOJ) were classified into four grades. Tomographic findings were compared with those for thirty control subjects. Results:The mean degeneration scores of C2-T1 facet joints and C2-C5, C7-T1 disc spaces were significantly higher in the cases of OSAS group than the cases of the control group. There were no significant differences in the mean degeneration scores for C5-6 and C6-7 cervical intervertebral disc levels between the groups. Degeneration scores of the facet and disc for whole cervical spine in the cases of the OSAS group was significantly higher than in cases of the control group (P<0.001 and P=0.002). AAOJ degeneration degrees showed differences between the groups. Statistically significant correlations were found between the OSAS degrees and the intervertebral disc degeneration (R=0.338, P=0.007) and facet joint degeneration (R=0.543, P=0.000) for all cervical vertebrae. Conclusions:The cervical spine of the OSAS patients has more severe disc degeneration and facet joint and AAOJ arthrosis, compared to subjects without OSAS. This findings may contribute to clinic evaluation of OSAS patients with servical pain and limited movement.
