A Beginner’s Guide to Neuroimaging
Neuroimaging is the process of using different methods to either directly or indirectly view the functioning, structure, or chemical makeup of your brain. It has been a relatively recent field in psychiatry, psychology, and neuroimaging.
It was used by neurologists, psychiatrists, and physicians for many years, but it wasn’t until the 1970s that neuroimaging really gained popularity. Today, neuroimaging is being used for a variety of reasons, ranging from neuropsychological studies to studying diseases, neurological disorders, mental disorders, and rehabilitation therapies.
There are various types of neuroimaging that are available. You can use neuroimaging to look at the brain through an ocular, positron emission tomography (PET), and/or functional magnetic resonance imaging (MRI).
The ocular technique utilizes special glasses to allow you to see inside of your brain
When performing neuroimaging technique, you need to have the ability to obtain images of your brain through two ways. The first is through direct imaging where your brain is imaged with a PET or MRI machine, and then you can view the results on the screen.
The second way that your brain can be imaged is through indirect imaging technique. In this method, your brain is imaged using a magnetoencephalograph, a neuroimager that uses magnetic fields to measure the activity of your brain neurons.
Through these two types of neuroimaging techniques, you can see how well your brain functions. Both types of neuroimaging will produce similar results, because they both are measuring the same functions, structures, and chemistry in the brain.
Certain types of neuroimaging can help determine whether there is something abnormal going on in your brain, but they cannot completely diagnose a disease
A doctor is not able to use neuroimaging to find out whether a patient is suffering from Alzheimer’s disease or has autism, nor can he or she tell if you are suffering from depression if you don’t share some of their behavior traits.
However, neuroimaging can be used to rule out the presence of conditions before testing them for symptoms. In order to prevent the occurrence of any health problems in patients during testing or clinical trials.
Neuroimaging can also reveal when the body is responding abnormally to drugs or alcohol. During neuroimaging, a positron emission tomography scan can show what the brain is producing for substances and/or proteins. in the bloodstream. A PET scan uses a radioactive tracer that is injected into the bloodstream to create the PET signal.
