I would not hesitate to recommend you or the firm to anyone in the future. Discography is used in conjunction with CT or MRI to localize disc herniation or fissure in the annulus fibrosis. A contrast agent is a liquid injected into your body to make certain tissues clearly visible during the imaging process. This test can determine if there is nerve damage and can how much. MRI scan for cauda equina syndrome These symptoms should prompt medical practitioners to suspect cauda equina syndrome. Having a standard approach to evaluating radiographs can help prevent a missed diagnosis; it is crucial to develop and maintain a specific sequence of observation. not be relevant to the changes that were made. The aim of this study was to compare the clinical characteristics of patients with and without abnormal MR imaging admitted to a neurosurgical unit with suspected cauda equina syndrome using a retrospective study of consecutive admissions to a regional neurosurgical unit over a 10-month period. X-rays, MRI lumbar spine without and with contrast, whole-body bone scan, CT lumbar spine without contrast, and CT myelography (contrast injected into spinal canal) may be appropriate. 2009 Nov 15;34(24):2711-3. doi: 10.1097/BRS.0b013e3181bd1e22. -, J Neurol Sci.

Compression of the cauda equina will result in certain clinical symptoms, most notably chronic back pain, urinary dysfunction and loss of sensation in the perineum/buttocks/upper legs. Imaging of the Spine. 1. For these reasons, a radiographic series may be the most appropriate screening examination. The position of the posterior-inferior corner of the fifth lumbar vertebra is then made relative to these divisions (Figure 4). A general set of rules cannot be applied to all patients, so physicians must properly evaluate each patient and use the appropriate diagnostic imaging tests judiciously. Because funds for medical testing are limited, physicians must fully understand the attributes and limitations of the various imaging modalities used for the evaluation of low back pain. While some may have had an alternative organic cause, we propose that these symptoms may have a "functional" origin in many patients. In cases of neurologic deficit, CT and/or MRI scans should be obtained to depict the spinal cord and surrounding tissue. Immediate imaging is also necessary if the patient hasor is suspected of havingcauda equina syndrome. Spontaneous spinal epidural hematoma (EDH) is a rare condition requiring urgent diagnosis (14).Patients with spontaneous spinal EDH typically present with acute onset of severe back pain and rapidly develop signs of compression of the spinal cord or cauda equina .Spinal EDH occurring spontaneously or after minimal trauma has been attributed most often to a venous source (57). Lumbar spine protocol (MRI) | Radiology Reference Article - Radiopaedia Cauda equina syndrome is a serious medical emergency, and compression of the nerves in the lower portion of the spinal canal causes it, and if left untreated it can lead to permanent loss of bowel and bladder control, parasthesia, and paralysis of the legs.

Appropriateness criteria | Low Back Pain - Radiologyinfo.org . no financial relationships to ineligible companies to disclose. SPECT scan differs from bone scan because it provides a three-dimensional image that enables physicians to locate the lesion more precisely. The best way to assess the cauda equina is with MRI of the lumbar spine with and without contrast medium. Signal characteristics of acute spinal epidural hematomas 1,2,5: Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. There were no significant differences between those with abnormal imaging (n = 34, 52%) and those with a normal scan (n = 32, 48%) in respect of sex, clinical history or features recorded on examination. A large number of patients present to neurosurgical units with symptoms suggestive of cauda equina syndrome without any radiological evidence of structural pathology. The axial image data can be reformatted to construct views of the scanned area in any desired plane. See spinal cord injuryand cauda equina syndrome for more information. Figures 18 and 2 are decision algorithms to guide the physician in the judicious use of imaging as a diagnostic tool for resolving low back pain. [1] 2. At the time the article was last revised Joachim Feger had As a result, the latter may require additional follow-up procedures to clarify abnormalities.
