A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, and organs. CT scans are more detailed than general x-rays. Head injury may cause the brain to swell. Since the brain is covered by the skull, there is only a small amount of room for it to swell. This causes pressure inside the skull to increase, which can lead to brain damage.
Intracranial pressure is measured in two ways.
The ICP device is then attached to a monitor that gives a constant reading of the pressure inside the skull. If the pressure goes up, it can be treated right away. While the ICP device is in place the patient will be given medication to stay comfortable. When the swelling has gone down and there is little chance of more swelling, the device will be removed. The extent of the person's recovery depends upon the type of brain injury and other medical problems that may be present.
