The World Health Organization says that 30 to 50% of cancers are preventable. The diagnosis of cauda equina syndrome generally is possible on the basis of medical history and physical examination findings. Misalignment of the spinous processes suggests a rotational injury such as unilateral facet dislocation. In addition to determining the available volume of the disc, discography is used to reproduce the symptoms associated with a possible herniated disc. Mullan C & Kelly B. This is because gadolinium dye is associated with increased risks to the fetus. Discography should be used cautiously because of the possibility of false-positive results. In showing the relative position of one bony structure to another, CT scans are also helpful in diagnosing spondylolisthesis. Cauda equina syndrome (CES) is a rare condition in which the .

Microscopic findings are shown in the figure, G-J. 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. By signing up you are agreeing to receive emails according to our privacy policy. In addition, radiation exposure limits the amount of lumbar spine that can be scanned, and results are adversely affected by patient motion; spiral CT addresses these weaknesses because it is more accurate and faster, which decreases a patients exposure to radiation exposure. Some examinations might profit from the improved spatial and contrast resolution of 3 tesla. If doctors suspect compression is being caused by an infection, they may choose to inject a harmless dye into the patient. More importantly, there were wide ranges among physicians: 2 to 48 percent for radiography; zero to 30 percent for CT, and zero to 9 percent for MRI.7. 4.

Thank you. Lesions of the vertebral body or spinous process are just as likely to be benign as malignant and, therefore, offer little diagnostic evidence.25, Gallium 67 is the most effective radioactive tracer in assessing infectious spondylitis. Although a significant variation can exist in the quality of lumbar spine MRI images as a function of the imaging center and the image interpreter,20 MRI is better than CT in showing the relationship of the disc to the nerve, and at locating soft tissue and nonbony structures. At the time the article was last revised Joachim Feger had Slight side effects such as dizziness, nausea, vomiting, pain at the injection site, and skin rashes are associated with contrast MRIs. Decreased disc space height can be indicative of disc degeneration, infection, and postsurgical condition. Discuss the fees associated with your prescribed procedure with your doctor, the medical facility staff and/or your insurance provider to get a better understanding of the possible charges you will incur. The patients response to pain can help confirm the source of the symptoms.

Bladder or bowel dysfunction some people continue to struggle with bladder and/or bowel control, even after surgical resolution of their CES. 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.

Recent advancements in technology have allowed noninvasive procedures such as CT and MRI to equal the accuracy of myelography in detecting herniated lumbar discs.12,13, The most important limitation of myelography is its inability to visualize entrapment of the nerve root lateral to the termination of the nerve root sheath. Patients who have experienced recent trauma should be considered for radiographic evaluation. Please type your comment or suggestion into the text box below. 2000;17 (3): 229-30.
