“…Of the several different imaging methods that are helpful in evaluation of the patients with radiculopathy, magnetic resonance imaging (MRI) is the preferred technique [7]. In patients with disc herniation, the resolution of symptoms with nonsurgical management has been reported to correlate with attenuation of the herniation on imaging studies [8,9].…”

Purpose The aim of this study was to evaluate the agreement of magnetic resonance imaging and electrodiagnostic studies by comparing their findings in patients with clinically suspected radiculopathy. The agreements between these two procedures and clinical findings were also examined. Methods In a 2-year cross-sectional study, a total of 114 patients with clinically suspected cervical or lumbosacral radiculopathy were included. Results The total agreements between clinical with MRI and EDX findings were 72 and 52 %, respectively while their agreements were similar in group definite (89 vs. 82 %). The agreement between EDX and MRI was 59.6 in total and 49 % with respect to clinical findings. Conclusion This study further supports that these two methods are complementary in general. It is reasonable to add EDX when there is discrepancy between MRI and clinical findings or when MRI neurologic findings are not visible.

“…MRI is routinely used for the evaluation of spinal degenerative diseases due to its ability to accurately delineate soft-tissue structures (e.g., intervertebral discs, spinal ligaments, neural elements) as well as osseous structures (e.g., vertebral bodies, spinal canals, facet joints, uncovertebral joints). The ability of MRI to detect subtle abnormalities in both soft tissue and bone makes it highly sensitive in the detection of any pathological features (Yu and Williams, 2006); therefore, it has largely replaced plain CT as the primary screening tool for cervical degenerative disease (Brown et al, 1988).…”

ABSTRACT. The aim of this study was to determine the reliability of magnetic resonance imaging (MRI) in the assessment of facet tropism and facet arthrosis of spondylolisthesis levels in degenerative cervical spondylolisthesis as compared to computed tomography (CT). The discrepancies in the interpretation of CT and MRI data in the evaluation of facet tropism and arthrosis have given rise to questions regarding the reliability of comparisons of the two techniques. Using a 4-point scale, 3 blinded readers independently graded the severity of facet tropism and facet arthrosis of 79 cervical facet joints on axial T2-weighted and sagittal T1 and T2-weighted turbo spin echo images as well as the corresponding axial CT scans. All results were subjected to the kappa coefficient statistic for strength of agreement. In the assessment of the severity of facet arthrosis, intermethod agreement (weighted κ) between CT scanning with a moderate inter-rater reliability (range κ = 0.43-0.57) and MRI with fair inter-rater reliability (range κ = 0.23-0.38) Evaluation of facet tropism and arthrosis was 0.76 and 0.43 for the severity of facet tropism and facet arthrosis, respectively. Intra-rater reliability for the severity of facet arthrosis was moderate to substantial for CT and was moderate for MRI scans. Intrarater reliability for the severity of facet tropism was substantial to very good for CT and substantial for MRI scans. MRI can reliably determine the presence or degree of facet tropism but not facet arthrosis. Therefore, for a comprehensive assessment of cervical facet joint degeneration, both a CT and an MRI scan should be performed.

“…Its high sensitivity for detecting disc disease [1][2][3][4] allows it to show degeneration in both symptomatic and asymptomatic patients. Boden et al 5 consider that abnormal MRI findings in asymptomatic subjects are false-positive results, since it is difficult to distinguish between ageing discs and pathologically degenerate discs which cause symptoms.…”

We studied degenerative changes in the cervical intervertebral discs of 497 asymptomatic subjects by MRI and evaluated disc degeneration by loss of signal intensity, posterior and anterior disc protrusion, narrowing of the disc space and foraminal stenosis. In each subject, five disc levels from C2-C3 to C6-C7 were evaluated.The frequency of all degenerative findings increased linearly with age. Disc degeneration was the most common observation, being present in 17% of discs of men and 12% of those of women in their twenties, and 86% and 89% of discs of both men and women over 60 years of age. We found significant differences in frequency between genders for posterior disc protrusion and foraminal stenosis. The former, with demonstrable compression of the spinal cord, was observed in 7.6% of subjects, mostly over 50 years of age.Our results should be taken into account when interpreting the MRI findings in patients with symptomatic disorders of the cervical spine.
