Scan Analysis #2

These series of images show the development of Alzheimer’s disease.  The left image is a PET scan that shows the normal levels of glucose metabolism (red and yellow) in the brain. As you can see, the levels of glucose metabolism are decreased in the second and third PET scan. The middle image shows the glucose metabolism decreased however the brain is still full. It is only a mild infection at the moment. This is when the patient may begin to forget things, that may seem normal to forget, however could progress into more severe memory loss.  Finally, the last image shows the patient’s brain as it has much less glucose metabolism than it did when it was normal. Also, if you noticed, now the scan has a big, black empty hole in the middle of the brain image than when it started. This is because the disease has gotten to the point where the patient isn’t able to remember very much. The development of the brain at this point is very low.

Scan analysis

This PET scan is showing the difference in brain images.  As you can see from the picture there are 4 different brain images all with difference pH readings.  The top, left image has a pH of 18. The top, right image has a pH of 19. The bottom, left has a pH of 24, and the bottom, right image has a pH of 25. These PET scans are used to show the amount of sugar compared to the acidity of the scans. The top, left image has the lowest pH and also has the least amount of sugar (represented by the yellow). The bottom, right image has the most yellow, as well as some green, which shows the severity of the amount of sugar. So you can see that as the pH is increased, the sugar is increased as well. As a result, this patient has medically uncontrollable seizures which are also known as epilepsy.
