Through CT scans, doctors use a combination of computer-processed x-rays and contrasting material to understand better the body’s bones, nerves, and muscles. In some cases, the doctor might opt to do a spinal tap if he can’t get enough information, but he will usually do an MRI first.
With MRI imaging, the biggest advantage of this technology comes from how it will provide you with crisp and clean scans of the body. The images are sharp and vivid, and they can often detect things like tumors and cancerous cells. In terms of Erb’s palsy, they can often tell you how much damage was done to the brachial plexus nerves. They might look to see if the nerve got torn away from the spinal cord of the child.
NCS, for short, doctors also call this nerve conduction studies. Through this system, doctors will measure how fast the electrical current passes through the nerve. Doctors like to perform this test to see how much damage was done to the individual’s nerve.
Normally, doctors will order an x-ray to determine if the child has Erb’s palsy or another condition. X-rays serve the primary purpose of looking for damage to internal organs and bones, but this can be used as a system for ruling out the possibility of broken bones before assuming a birth disorder. Most x-rays can’t tell you anything about the nerves, however.
