1. Radiographic evidence of degenerative change is most common in patients older than 40 years and is present in more than 70 percent of patients older than 70 years.9 Degenerative changes have been reported to be equally present in asymptomatic and symptomatic persons.9 The incidence of intervertebral narrowing and irregular ossification of the vertebral end plates has also been shown to be associated with increased age.10 Even though plain radiographs usually provide little definitive information, they should be included in the screening examination for patients with certain red flags (Table 1).8.

Morita M, Miyauchi A, Okuda S, Oda T, Aono H, Iwasaki M. J Spinal Disord Tech. contrast MRI, a frequency similar to that seen in intracranial meningiomas (19,20). T2-weighted spin echo images enhance the signal of the cerebrospinal fluid, making this series more sensitive to spinal pathology (such as tumor, infection, osteomyelitis, and discitis), but it is often more time consuming with the pulse sequence. The myelogram may show herniated discs, bone spurs, or tumors, all of which may be responsible for causing CES. There are 10 references cited in this article, which can be found at the bottom of the page.

It is also useful in patients who are claustrophobic or have a pacemaker, or for whom MRI is otherwise contraindicated. 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. At least one T1-weighted sequence should be included to ease the assessment and interpretation of bone marrow and/or soft tissue lesions. However, to qualify as CES there must be evidence of S2-S4 nerve . Spin echo is the standard pulse sequence when using T1-weighted images, which are commonly used to contrast tissues such as neural foramina and nerve roots.
