Is traumatic brain injury (TBI) diagnosed using MRI or a CT scan?

There is no single test used when physicians attempt to diagnose TBI and TBI does not always show up on a CT scan or an MRI. That is why there are a number of other tests done to help diagnose TBI.

Below is a list containing a number of tests that can be used in a diagnosis of TBI:

• Vision tests
• Hearing tests
• Blood tests
• X-rays
• Psychological tests
• CT scans
• MRI
• SPECT scans
• PET scans
• EEG
