Recent studies25,26 have evaluated the ability of bone scans, with the addition of single-photon emission computed tomography (SPECT), to distinguish benign lesions from malignant lesions. 4. While some may have had an alternative organic cause, we propose that these symptoms may have a "functional" origin in many patients. SPECT scan differs from bone scan because it provides a three-dimensional image that enables physicians to locate the lesion more precisely.

For these reasons, a radiographic series may be the most appropriate screening examination. The contrast allows clear visualization as to whether there are any abnormalities or displacements in your spinal column. Some patients will not be able to have an MRI scan for medical reasons. The limitations of CT include less-detailed images and the possibility of obscuring nondisplaced fractures or simulating false ones. Patient history and physical exam: Extremely important to assess for cauda equina syndrome. Although bilateral sciatica is the classic "red flag" symptom for cauda equina syndrome (CES), it is present in only about 50% of cases. 2 0 obj % Typically there will be a combination of severe pain and neurological deficit. Patients with infection or tumor should be initially screened with plain radiographs followed by MRI. 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. The best way to assess the cauda equina is with MRI of the lumbar spine with and without contrast medium. Computed tomographic scanning is useful in demonstrating osseous structures and their relations to the neural canal, and for assessment of fractures. (MRI) with and without contrast should be obtained to identify any possible mass lesions. Physical examination reveals low back pain with bilateral weakness of the lower extremity, saddle anesthesia, and bowel and bladder incontinence.

These compounds are incorporated into hydroxyapatite crystals that are deposited in an osteoid matrix during new bone formation. References. 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.

A typical MRI of the lumbar spine might look as follows: The mainstay in spinal imaging is T1 weighted and T2 weighted images 2. or enter your details below and we will be pleased to answer your questions and advise you of your options. CT without contrast may be useful if MRI is not available or contraindicated. NSF is a rare disease occurring in patients with pre-existing severe kidney function abnormalities. MRI without and with contrast and CT myelography may be appropriate. Generally, non-contrast imaging is popular with most orthopedic studies, since the imaging comes out clear without the contrast dye. 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. Very sensitive on personal injuries. Lumbosacral MRI with and without contrast should be obtained and may demonstrate .
