UCSF neurology specialist Dr. David M. Norelli is leading a team that is studying whether there are differences in how brain scans of patients and healthy volunteers perform.
The team, led by Dr. Noren, is currently investigating whether there is a difference in how MRI brain scans and brain images of patients perform.
Dr. Nometlli says there are many different ways to measure the health of the brain.
He says it is critical to understand the process of the blood flow, how the brain responds to various stimulation, and how different neural networks communicate.
The team is looking at how a patient with cerebral palsy responds to stimulation, whether it is a positive or negative, and whether a patient has any symptoms associated with the condition.
Norelli says the team has identified a number of differences in the way the brain is functioning in patients with brain injury and in healthy people.
One difference is that the brain of a brain injury patient appears to have a greater concentration of blood vessels than that of a healthy person.
Dr. M. David Norellini says this difference is probably related to the fact that the injury is in the brain rather than in the muscles, and the muscles have more blood supply to them.
Dr Norello says it would be interesting to find out if the differences in brain anatomy are related to how patients respond to the stimulation or to whether they have other conditions that would affect the blood supply in the nerves.
Another difference is the degree of activation of different areas of the cerebral cortex, including the prefrontal cortex, which is important for higher cognitive functions.
For example, when a person is depressed, the prefrontal cortical region is activated.
When Dr. Michael S. O’Neill, MD, the lead author of the study, is on the operating table, he says he is doing a lot of work that will help him figure out what happens in the brains of people who have brain injuries.
He is looking for ways to improve the accuracy of the MRI and the brain scans so that they can be more sensitive to the symptoms of brain injury.
O’Neill says if the MRI brain scan does not detect the condition as a diagnosis, it will be difficult to determine whether it has occurred or not.
He wants to make sure that the MRI is very precise.
Ollenhorst says he has been studying how the different areas respond to different stimuli.
He uses the MRI to see how different areas react.
Dr O’Nellini says his team is focused on developing better imaging technology, but he thinks there are some potential ways to make MRI scans more accurate.
He sees these techniques as a first step.
David Norella says he would like to see the imaging technology used to make the brain scan more accurate, so that it can be used in a much more timely fashion to make a diagnosis.
