Interactive 2D and 3D review of a brain SPECT demonstrating TBI.

What is TBI?
Traumatic brain injury usually results from a violent blow or jolt to the head or body. An object that goes through brain tissue, such as a bullet or shattered piece of skull, also can cause traumatic brain injury.
Mild traumatic brain injury may affect your brain cells temporarily. More-serious traumatic brain injury can result in bruising, torn tissues, bleeding and other physical damage to the brain. These injuries can result in long-term complications or death.

TBI Physical Symptoms:
Nausea or vomiting
Fatigue or drowsiness
Problems with speech
Dizziness or loss of balance

TBI Sensory Symptoms:
Sensory problems, such as blurred vision, ringing in the ears, a bad taste in the mouth or changes in the ability to smell
Sensitivity to light or sound

TBI Cognitive/Mental Symptoms:
Loss of consciousness for a few seconds to a few minutes
No loss of consciousness, but a state of being dazed, confused or disoriented
Memory or concentration problems
Mood changes or mood swings
Feeling depressed or anxious
Difficulty sleeping
Sleeping more than usual

Value of SPECT
The value of SPECT in evaluating traumatic brain injury is the ability to locate the specific areas of the brain that are affected as well as asses the severity. Based on the location of the abnormalities a more effective treatment plan can be established. Because SPECT is a functional imaging modality, it can detect changes in the brain long before they can be observed in anatomical imaging (CT/MR).
