What tests are used to diagnose a brain injury?

When diagnosing a brain injury in California, a variety of tests are used to accurately determine the extent of the damage. Common tests are computerized tomography (CT) scans and magnetic resonance imaging (MRI). During a CT scan, a series of x-rays are taken from different angles in order to create a detailed 3D image of the brain. An MRI uses a large magnet and radio waves to create detailed images of the brain as well. Both CT and MRI scans can reveal tumors, bleeding, and other damage to the brain and skull. In addition to scans, physicians may also use cognitive tests like the Glasgow Coma Scale. The physician will observe the patient’s responses to things such as verbal and physical stimulation. The physician will then give a score, which will indicate the severity of the injury. Other tests like the Rancho Los Amigos Scale may also be used to assess the severity of the injury and the patient’s recovery. Lastly, brain imaging tests like single photon emission computed tomography (SPECT) or positron emission tomography (PET) can be used to measure blood flow and activity in the brain. This helps to identify any areas of the brain that aren’t working properly. The results of these tests can help physicians decide on the best course of treatment for the patient.
