SPECT scans the brain looking at the blood flow and follows activity patterns that forms to render an image that shows us how the brain works. We render two scans – the first which shows the brain at rest and the other during concentration. The images above shows two different brains with different SPECT renderings, one healthy and the other unhealthy that displays various disorders.
A healthy brain is achieved with a balanced lifestyle that includes adequate sleep, proper diet, and physical activity. Things like stress, drugs and alcohol and lack of sleep or proper exercise are harmful to the brain.
Healthy vs Unhealthy
On the SPECT rendering a healthy brain would show the a smooth brain surface with proper blood flow to all parts of the brain and full activity. This is a good example of the way the brain is supposed to be working.
The SPECT rendering of an unhealthy brain revels many “holes” or “dimples” on the surface of the brain which shows lack of blood flow and poor activity in brain function. Unhealthy brain shows a history of substance and/or alcohol abuse which causes damage to the brain.
