I am going to include the 3 SPECT scans that Bryan had done in New Orleans, the first scan is before treatment, second is after 1 treatment of HBOT, and the last is after 40 treatments. They will be inserted in that order. Please click on pictures for a bigger view. Below that I will include the explanation that Dr. Harch included as well as the notes I took on the call we had yesterday.
Brain Scan 1
On each print of each scan are the transverse slices of the brain blood flow images on the right and the three dimensional reconstruction of the slices on the left. There are 4 views of the 3-D reconstruction. When looking at the transverse slices of each scan date remember that you are looking at each scan slice from your feet so that the right side of each slice image on the paper, as you are looking at it, is the left side of your head and vice versa. The slice image is in the position you were laying on the scanning table so that the top of each slice image is your face and the bottom is the back of your head.
The color format is white/yellow, orange, purple, blue, and black in descending order of blood flow. The scanner computer picks the area of highest brain blood flow and gives it a relative value of 100. All of the remaining little voxels (cubes) of brain blood flow are referenced to this value of 100 so that the scan gives a picture of each brain area's blood flow in relation to the rest of the brain. The most important finding is smoothness of each slice or balance of blood flow in the brain. In other words, normal is the least variation in colors. Abnormal is when you have bright white/yellow areas alternating with orange, purple, or blue. The effect of HBOT is to cause the brain to function more normally and have a very narrow range of brain blood flow. This translates to a color map that is smooth, i.e., very little alternation between high and low blood flow. If you look at the two scans side by side you will see a smoothing effect after HBOT. This usually correlates with a person feeling and thinking better.
The three dimensional pictures are a computer reconstruction of the outermost voxels on the entire surface of the brain using the transverse images. Most of the time, but not always, if the transverse images show the smoothing effect after HBOT (again, the most important finding) it will be captured as an improvement in the 3-D images. The 3-D's show four views of the brain: front, both sides, and top. When there is a significant reduction in brain blood flow the computer will register it as a "hole." It is not a real hole in your brain; it is just a method to visualize the areas of injury or areas that, in general, are not working well as a result of your injury. Most of the time the 3-D's show improvement in the areas of significant deficits in blood flow after HBOT. Sometimes there is some rearrangement of blood flow such that some small holes can appear after HBOT. This is not significant. The other finding of importance is that the high/low variation in blood flow described above on the transverse slices gets translated to a "rough" appearance of the surface of the 3-D's. In almost every case after HBOT the surface of the 3-D appears smoother. The rule of thumb is that the transverse brain slices truly register the injury and the 3-D usually is consistent with the transverse slices. If it is not don't be concerned because the 3-D is not an exact measurement. It is a visual tool to help you read brain blood flow in your brain at the time of the imaging.
Also included is a copy of your neuropsychological (cognitive) test scores before and after HBOT as well as your PTSD and quality of life questionnaire scores.
It is going to be hard to compare these side by side. However you can see the brain damaged areas, yellow and white get better even after 1 treatment. Dr. Harch stated that they saw one of the biggest improvements after just 1 treatment. He had a huge color change in the 5th and 6th rows on the first and second scans.
The "hole" indicated that the frontal and temporal lobes were damaged. These are most common with memory loss. The brain injury was all over which is common with IED brain injuries but there was more damage in the frontal lobe with a emphasis in the left. He said that there was a remarkable change in the imaging and he fit the study perfectly. He said this injury was very real and the problems that he was having were definitely from the TBI. It was nice to feel validated and get treatment when Walter Reed basically said wait two years and if it doesn't get better that's as good as you will get.
On the neuropsychological test evaluation. His IQ improved 6 points on the pre and post tests. There are areas that can't be learned or practiced and he improved vastly in these areas. He improved in the peg board, auditory memory, and verbal (the biggest thing that improved).
Bryan's depression index went down 19% and this is the biggest they have ever seen. His anxiety also went down considerably. His PTSD also went down and his symptoms of depression and anxiety went down.
Finally he said that there will be residual problems and suggested 40 more treatments to improve his brain. He said that Tricare has been paying for these and if he needed help let him know. Aging, like I mentioned in my last depressing post, can become quicker with cognitive problems. He said that don't let the doctors think he is crazy when he starts having problems and demand more HBOT. Right now we will be shooting for 40 more treatments with a random 6 or so maintenance treatments per year.
Sorry if this is confusing (I don't understand a lot of it myself) but wanted to share to let other's know there is hope. Things can get better and there is a treatment for this without eating a bunch of pills. I am so thankful and have been quite emotional since we went over all this yesterday. With his Alive Day coming up and being validated and knowing this helped. I feel so blessed.
