Myelography is a type of radiographic examination that uses a contrast medium (e.g. iodised oil [1]) to detect pathology of the spinal cord, including the location of a spinal cord injury, cysts, and tumors. Historically the procedure involved the injection of a radiocontrast agent into the cervical or lumbar spine, followed by several X-ray ...
The patient should be adequately hydrated to remove contrast from the body. The patient should be observed following the examination for adverse effects of contrast media. The myelogram is performed on an outpatient basis, So the patient should be properly instructed regarding limitations following the procedure such as driving.
Diffusion imaging is an MRI method that produces in vivo magnetic resonance images of biological tissues sensitized with the local characteristics of molecular diffusion, generally water (but other moieties can also be investigated using MR spectroscopic approaches). [15]
Disc herniation can occur in any disc in the spine, but the two most common forms are lumbar disc herniation and cervical disc herniation. The former is the most common, causing low back pain (lumbago) and often leg pain as well, in which case it is commonly referred to as sciatica .
Spinal cord injury without radiographic abnormality (SCIWORA) is symptoms of a spinal cord injury (SCI) with no evidence of injury to the spinal column on X-rays or CT scan. [4] [5] Symptoms may include numbness, weakness, abnormal reflexes, or loss of bladder or bowel control. [2] Neck or back pain is also common. [3] Symptoms may be brief or ...
In contrast, the motor and sensory nerve conduction studies evaluate conduction in the segment of the limb. F waves vary in latency and an abnormal variance is called "chrono dispersion". Conduction velocity is derived by measuring the limb length, D, in millimeters from the stimulation site to the corresponding spinal segment (C7 spinous ...
The spine (that is, the vertebral column. A projectional radiograph of the spine confers an effective dose of approximately 1.5 mSv, comparable to a background radiation equivalent time of 6 months. Cervical spine: The standard projections in the UK AP and Lateral. Peg projection with trauma only.
Spinal stenosis may also affect the cervical or thoracic region, in which case it is known as cervical spinal stenosis or thoracic spinal stenosis. Lumbar spinal stenosis can cause pain in the low back or buttocks, abnormal sensations, and the absence of sensation (numbness) in the legs, thighs, feet, or buttocks, or loss of bladder and bowel ...
