A CT scan is typically performed after radiographic contrast media (dye) has been placed with fluoroscopic guidance into a sac-like lining (the first- and hardest and outermost- layer of the spinal meninges, the spinal dura mater) surrounding the spinal cord and nerves. The material is typically water-soluble, which has largely replaced ...
Quantitative CT scans are primarily used to evaluate bone mineral density at the lumbar spine and hip. In general, solid phantoms placed in a pad under the patient during CT image acquisition are used for calibration. These phantoms contain materials that represent a number of different equivalent bone mineral densities.
Lumbar spinal stenosis (LSS) is a medical condition in which the spinal canal narrows and compresses the nerves and blood vessels at the level of the lumbar vertebrae. Spinal stenosis may also affect the cervical or thoracic region, in which case it is known as cervical spinal stenosis or thoracic spinal stenosis.
Physically demanding jobs, contact sports and being overweight can increase risk of developing lumbar spondylosis. Lumbar spondylosis diagnosis can be made by physical exam, symptom tracking, MRI ...
She was administered a CT scan, and medics advised she receive a lumbar puncture to eliminate the possibility of a hemorrhage. However, she declined, “self-discharged” from the hospital and ...
A computed tomography scan (CT scan), formerly called computed axial tomography scan (CAT scan), is a medical imaging technique used to obtain detailed internal images of the body. [2] The personnel that perform CT scans are called radiographers or radiology technologists.
In CT myelography, spinal tap is performed in the low back with dye injected into the spinal fluid. X-rays are performed followed by a CT scan of the spine to help see narrowing of the spinal canal. This is a very effective study in cases of lateral recess stenosis.
Even though the CT scan allows for intensive image studying, the fixed nature of the image collection process alone is not enough to reach a definitive diagnosis of lumbar spinal stenosis. The outcome of the CT scan can help compile physiological evidence that the patient has lumbar spinal stenosis, and that the patient may potentially benefit ...
