Clipboard, Search History, and several other advanced features are temporarily unavailable. Degenerative changes are often evident on plain radiographs; however, caution must be used in making a diagnosis based on degenerative radiographic changes because of the high rate of asymptomatic degenerative changes. Explained everything. The MRI scan should clearly show whether or not the cauda equina nerves are being compressed. The AP view of the lumbar spine should include the whole pelvis; this allows for evaluation of the acetabulum and femoral heads and for the detection of possible degenerative changes to the pelvis. Both MRI with and without contrast are non-invasive and painless. If the lumbar vertebra is completely anterior to the sacral base, spondylolisthesis has occurred. 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. A CT scan performed within two hours of completing myelography enhances the diagnostic quality and reliability of the imaging study by more accurately depicting osteophytes, disc herniations, and spinal cord contour.11, Myelography is an invasive technique and lacks diagnostic specificity. ACRASNRSCBT-MRSSR Practice Parameter for the Performance of Magnetic Resonance Imaging (MRI) of the Adult Spine.

Cauda equina syndrome | The BMJ Gadolinium is thought to enhance the appearance of nerve roots in viral or inflammatory conditions and can help distinguish recurrent disc herniation from scar tissue in the postoperative spine.24. Pathology of the cauda equina can arise from a nerve root, pia mater, or arachnoid space. They are not as useful as MRI in visualizing conditions of soft tissue structure, such as disc infection.

Postoperative examinations in patients with metallic implants, however, should be done on 1.5 tesla with a metal artifact reduction sequence (MARS). It is thus unable to detect any far lateral disc herniations, which reportedly account for 1 to 12 percent of all lumbar disc herniations and occur most often at the L4-L5 and L3-L4 levels.14,15, Possible side effects of myelography include dural tear, which can cause headaches, nausea, vomiting, pain or tightness in the back or neck, dizziness, diplopia, photophobia, tinnitus, or blurred vision.16,17 It is thought that a dural tear can result in a loss of cerebrospinal fluid volume, decreasing the brains supporting cushion, so that when the patient is standing there is tension on the brains anchoring structures.18 A persistent postmyelography headache can be treated with an epidural blood patch, in which 10 to 20 mL of autologous blood is injected into the epidural space under sterile conditions.19.
