Guest guest Posted January 30, 2003 Report Share Posted January 30, 2003 Can someone please explain what a Spect can does, as compared to a QEEG? This would be for a group of parents interested in RAD and NF, so no need to get overly technical. Thanks, D Quote Link to comment Share on other sites More sharing options...
Guest guest Posted January 30, 2003 Report Share Posted January 30, 2003 , A spect scan is a nuclear imaging technique. The brain uses the glucose in the blood as its " fuel " . To do a spect scan a person is given a glucose solution with a radioactive marker. As the brain works harder it takes up more glucose, resulting in an increased amount of the radioactive material. The equipment used in the spect scanning process measueres the amount of radioactivity in every area of the brain and can create a 3d model of the brain with different colors reflecting the amount of activity. What this results in is a picture of the metabolic function of the brain. This picture looks at both surface and deep structure activity. Spect scans can be done in a resting state or under task. Much of the spect scan work done with adhd is done with both conditions showing the marked differences in brain activity in task/nontask conditions. www.brainplace.com has a good explanation of spect scans as well as a library of many spect images in people differnt conditions. The one thing a spect scan shows that a qeeg does not is the deep structure activity. The qeeg is restricited to surface activity.
