No concerning extraspinal finding. The most common type of CT scan with contrast is the double Only radiographic parameters with near-perfect agreement were used for radiographic indices and underwent receiver operating characteristic (ROC) analysis to identify the cutoff values that diagnose subjects with DSS. Similarly, ABW:IPD was calculated for the AP radiograph (Table3). The indications for ultrasonography of the neonatal/infant spinal canal and its contents include, but are not limited to [2-14]: 1.

Degenerative changes in the spine have high medical and socioeconomic significance. Other associations include spondylolisthesis, scoliosis, vertebral erosions, and vertebral fractures. Patients having wide canals are more likely to have less neurological dysfunction than those having narrow canals. If neural structures are compressed, treatment consists of reduction (traction or changes in head position to realign the craniocervical junction and thus relieve neural compression). Although it is impossible to measure the exact width of the pedicle depicted on lateral radiographs, two consistent landmarks (facet joints and posterior vertebral body) are used to help guide us to where the pedicle should be. A craniocervical abnormality is suspected when patients have pain in the neck or occiput plus neurologic deficits referable to the lower brain stem, upper cervical spinal cord, or cerebellum.

The clinical spectrum of lumbar spine disease in achondroplasia. These were the most consistent landmarks visible on lateral radiographs. Lower cervical spine disorders can usually be distinguished clinically (based on level of spinal cord dysfunction) and by neuroimaging. Diagnosis is by MRI. Role of Radiological Investigations in Diagnosis of Spinal - Springer Moreover, no description has been made regarding how radiographic measurements were performed limiting relevance of their findings to actual developmental narrowing of the bony spinal canal. Radiol Clin North Am. injuries and/or diseases of the spine. HHS Vulnerability Disclosure, Help (2011) ISBN: 9780702033957 -, 2. Arbit E, Pannullo S. Lumbar stenosis: a clinical review. The results from this study suggest that DSS plays an important role in the pathogenesis of symptomatic lumbar spinal stenosis.

If contrast media is used, there is a risk for allergic reaction to the Landis JR, Koch GG. Hirayama-like disease in the thoracic spine - ScienceDirect These abnormalities can result in neck pain; syringomyelia; cerebellar, lower cranial nerve, and spinal cord deficits; and vertebrobasilar ischemia. include , Ifnot related to overall skeletal size, could canal dimensions be . Although this can be theorized from our results, at present, these indices can only serve as reference for identifying subjects with narrowed spinal canals without further longitudinal follow-up of these asymptomatic individuals. The limitation of this study is the lack of longitudinal data. All subjects underwent lumbar AP and lateral standing radiographs of the lumbosacral spine (view of the thoracolumbar region to sacrum) extracted to measure parameters including interpedicular distance (IPD) and axial vertebral body height and width (ABW) on AP views (Fig. the length of the procedure might cause some discomfort or pain, Developmentally, the pedicle is the main reason for a narrowed spinal canal. Please enable it to take advantage of the complete set of features! CT scans are more line will be removed. To understand how a developmentally narrowed spinal canal correlates with symptoms requires further understanding of phenotypic differences between symptomatic and asymptomatic DSS as well as longitudinal follow-up studies to determine any age-related effects on measurement parameters. 2011;69:3037. All subjects were consented to participate. upper part of the lower back. For the lateral radiograph, SBW:PW and SBW:PPM ratios were calculated. What is a CT scan of the spine?

All data generated or analyzed during this study are included in this published article. commonly used imaging method for the ac-curate evaluation of spinal canal stenosis. The Canal is capacious. Contrast examinations may require you to fast for a certain period of time The effects of kidney disease and contrast agents have 1964 May;91:1036-50 Craniocervical junction abnormalities are congenital or acquired abnormalities of the occipital bone, foramen magnum, or first two cervical vertebrae that decrease the space for the lower brain stem and cervical cord. Spine J. Subject identification can be based on a simple radiograph which, as a screening tool, is more cost-efficient and is more readily available than MRI. Lumbar spinal stenosis. Thus, the aim of this study is to develop radiographic indices for diagnosing DSS. Other imaging-based criteria have been suggested in the past [7, 8, 1017] but were based on inconsistent imaging modalities [8, 10, 13, 16, 17], heterogeneous populations [8, 10, 11, 13, 16, 18, 19], lacked control groups [8, 10, 11, 13, 19], and generalized measurements of the entire lumbar spine [8, 10, 11, 13, 1619]. Neck pain Evaluation of Neck and Back Pain Neck pain and back pain are among the most common reasons for physician visits. Correspondence to There is also an increased incidence of anterior sacral meningoceles which may present as an abdominal mass.
