Objective: This study was conducted to describe the patterns of radiographic and MRI changes in subjects with degenerative disc of the lumbar spine. Materials and Method: a cross-sectional study was done in a sample of 212 individuals who had been diagnosed degenerative disc on MRI sagittal T2 FSE. The degree of degeneration was classified into 5 grades according to Pfirrmann’s classification. All individuals underwent clinical examination, lumbar conventional radiograph and lumbar MRI using 0.23T Open MRI system. Peridiscal lesions such as discal herniation, thecal sac compression, canal stenosis, vertebral osteochondrosis, Modic change and Schmorl’s node were also included in this study. Results: The result showed the proportion of subjects with lumbar disc degeneration by age. The rate was highest in the age group ³ 50 (45.4%) and lowest in the age group <30 (12.7%). There was no significant difference between male and female (χ2 = 2,42; p=0,12). The most common finding of lumbar radiograph was osteophytes (77.4%; p<0.001). There was a correlation between age, osteophytes, disc space narrowing with the degree of degeneration. Cut-off value for age was estimated > 47 (Se=73.4%, Sp=76.1%) with area under ROC curve was 0.806. The most usually affected level was found to be L4-L5 (31.8%). Most of degenerated disc were classifies as grade III (59.5%). Subjects with 1 or 2 degenerative levels made the definitely higher rate compared to 4 or 5 levels. Common peridiscal lesions were disc herniation, canal stenosis, thecal sac compression, vertebral osteochodrosis, Modic change and Schmorl’s node (respectively). Conclusion: The prevalent rate and degree of disc degeneration increased by age meaning that age is risk factor for disc degeneration. Lumbar radiograph and MRI are useful in the evaluation of degenerative disc disease. Key words: lumbar intervertebral disc degeneration, magnetic resonance imaging.

Abstract Objective: To determine the prevalence of incidental findings on magnetic resonance imaging (MRI) scans of the cervical, thoracic and lumbar spine in a paediatric population. Materials and Methods: We evaluated 190 spinal MRI examinations of patients aged ≤ 18 years of age. The study included only patients for whom complete medical records were available and who underwent complete MRI examination of the cervical, thoracic or lumbar spine, including whole-spine sagittal T2-weighted sequences. Imaging findings not related to the symptom or indication for MRI were considered incidental findings. Results: Of the 190 MRI examinations evaluated, 110 were in women and 80 were in men. The mean age of the study population was 12.46 ± 3.68 years. The main clinical indications for MRI in the sample were lumbago, scoliosis, dorsalgia and cervicalgia. Incidental findings were detected in the cervical, thoracic and lumbar spine in 40 (21.05%), 26 (13.83%) and 43 (22.63%) of the patients, respectively. The most common were (in the cervical spine) reversal/correction of the normal curvature; (in the thoracic spine) intravertebral disc herniation (Schmorl’s node) and disc dehydration; and (in the lumbar spine) disc protrusion (12 cases), Schmorl’s node (5 cases) and spondylolysis (4 cases). Conclusion: Incidental findings on MRI of the spine are less common in the paediatric population than in the adult population. Nevertheless, careful clinical evaluation of paediatric patients with complaints of axial and radiating pain is necessary in order to determine the correlation between symptoms and imaging findings.

Pfirrmann Score

Magnetic resonance imaging (MRI) is the golden standard technique for spine disc disease diagnosis. Vertebral body endplate signal intensity on MRI is confirming lumber spine degenerative disc disease.The study aimed to record the lumbar spine degenerative relation between disc and diseaseusing magnetic resonance imaging. Our prospective and double blind investigation included 142 participants,having lumbar spine degenerativedisease confirmed by MRI. Pfirrmann score was used to record the relation between lumbar spine disc degeneration and lumbar spine degenerative disease. Modic modifications with the Pfirrmann and modified Pfirrmann scores of disc degeneration were assessed.Lumbar spine MRI was done for all participants using sagittal T1 and T2 WI. Modic was scored (0-III) The Pfirrmann scored I-V for disc degeneration. Lumbar disc degeneration was evaluated by modified Pfirrmann scoring from 1-8 according to signal intensity of the nucleus pulposus and inner annulus.Modic was recorded in 41.5%, 24.6%, 32.4% and 1.4% of participants with scores 0, I, II and III, respectively. Pfirrmann score was 13.4%, 73.9% and 12.7% of disc degeneration with scores III, IV and V, respectively, while,the modified Pfirrmann score was 2.1%, 15.5%, 38.7%, 26.8% and 16.9% of disc degeneration with scores of 4, 5, 6, 7 and 8, respectively. The modified Pfirrmann score showed notableinconsistencyin participants with Modic 0, I and II, but no difference between Modic I and II.There was significant relation between Modicand lumbar spine disc degeneration. In conclusion, there is a relation between Modic, Pfirrmann and modified Pfirrmann scores of lumbar spine disc degeneration in participants with lumbar spine degenerative disease.

AbstractObjectives:The bony cochlear nerve canal is the space between the fundus of the internal auditory canal and the base of the cochlear modiolus that carries cochlear nerve fibres. This study aimed to determine the distribution of bony labyrinth anomalies and cochlear nerve anomalies in patients with bony cochlear nerve canal and internal auditory canal atresia and stenosis, and then to compare the diameter of the bony cochlear nerve canal and internal auditory canal with cochlear nerve status.Methods:The study included 38 sensorineural hearing loss patients (59 ears) in whom the bony cochlear nerve canal diameter at the mid-modiolus was 1.5 mm or less. Atretic and stenotic bony cochlear nerve canals were examined separately, and internal auditory canals with a mid-point diameter of less than 2 mm were considered stenotic. Temporal bone computed tomography and magnetic resonance imaging scans were reviewed to determine cochlear nerve status.Results:Cochlear hypoplasia was noted in 44 out of 59 ears (75 per cent) with a bony cochlear nerve canal diameter at the mid-modiolus of 1.5 mm or less. Approximately 33 per cent of ears with bony cochlear nerve canal stenosis also had a stenotic internal auditory canal and 84 per cent had a hypoplastic or aplastic cochlear nerve. All patients with bony cochlear nerve canal atresia had cochlear nerve deficiency. The cochlear nerve was hypoplastic or aplastic when the diameter of the bony cochlear nerve canal was less than 1.5 mm and the diameter of the internal auditory canal was less than 2 mm.Conclusion:The cochlear nerve may be aplastic or hypoplastic even if temporal bone computed tomography findings indicate a normal cochlea. If possible, patients scheduled to receive a cochlear implant should undergo both computed tomography and magnetic resonance imaging of the temporal bone. The bony cochlear nerve canal and internal auditory canal are complementary structures, and both should be assessed to determine cochlear nerve status.

In imaging diagnosis, redundant nerve roots of the cauda equina are characterized by the presence of elongated, enlarged and tortuous nerve roots in close relationship with a high-grade lumbar spinal canal stenosis. This is not an independent entity, but it is believed to be a consequence of the chronic compression at the level of the lumbar canal stenosis and thus may be part of the natural history of lumbar spinal stenosis. The present paper is aimed at reviewing the histopathological, electrophysiological and imaging findings, particularly at magnetic resonance imaging, as well as the clinical meaning of this entity. As the current assessment of canal stenosis and root compression is preferably performed by means of magnetic resonance imaging, this is the imaging method by which the condition is identified. The recognition of redundant nerve roots at magnetic resonance imaging is important, particularly to avoid misdiagnosing other conditions such as intradural arteriovenous malformations. The literature approaching the clinical relevance of the presence of redundant nerve roots is controversial. There are articles suggesting that the pathological changes of the nerve roots are irreversible at the moment of diagnosis and therefore neurological symptoms are less likely to improve with surgical decompression, but such concept is not a consensus.
