When your involved in a collision you may discover that your injuries aren’t necessarily obvious in the first wave of diagnostics. You should be aware that certain tools, such as x-rays, may not tell the whole story about your your injuries.
You want to ensure that your injuries have been properly diagnosed so you are aware of the level of compensation you should be entitled to.
While x-ray images are among the clearest and most detailed views of bone, they provide little information about nerves, muscles, tendons or joints. X-rays can certainly be a starting point for investigations into back and neck injuries.
An MRI may be more useful in identifying ligament tears and joint effusions in knee, spine, or shoulder injuries, because both the bones and the spinal cord can be evaluated. Did you know that the MRI is capable of detecting a bone bruise when no crack is visible on x-ray images?
CT is being used widely to assess trauma patients in emergency departments. A CT scan can image complicated fractures, subtle fractures or dislocations. In elderly or patients with osteoporosis, a hip fracture may be clearly seen on a CT scan, while it may be barely seen, if at all, on a hip x-ray.
For suspected spine injury, 3-D reconstructed CT images can be made without additional radiation exposure to help the diagnosis and treatment of the individual patient’s condition.
Finally, there’s another tool called ultrasound imaging, which uses sound waves instead of ionizing radiation to create diagnostic images. It too has been useful for injuries around joints.
