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.
Clearing the cervical spine is the process by which medical professionals determine whether cervical spine injuries exist, mainly regarding cervical fracture. It is generally performed in cases of major trauma. This process can take place in the emergency department or in the field by appropriately trained EMS personnel.
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.
CT scan of the spine, showing calcification of the longitudinal posterior ligament. Because laboratory testing lacks specificity, MRI with and without contrast media and often, biopsy are essential for accurate diagnosis [37]
At a cost of US$600 to $3000, full-body scans are expensive, and are rarely covered by insurance. [10] [11] However, in December 2007, the IRS stated that full-body scans qualify as deductible medical expenses, without a doctor's referral. This will likely lead employer-sponsored, flexible-spending plans to make the cost of the scans eligible ...
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]
