An MRI scan reveals the gross anatomical structure of the human brain.(Image credit: Courtesy FONAR Corporation) Protons in different body tissues return to their normal spins at different rates, so the scanner can distinguish among various types of tissue. The scanner settings can be adjusted to...
If your doctor suspects a brain tumor, an MRI is the best way to detect it. MRIs provide more detailed information on brain tumors than CT scans. A test called magnetic resonance spectroscopy can be part of the MRI. It compares a tumor to normal brain tissue, which can help reveal the ...
Our human brain has 100 trillion connections or parameters. But one trillion, just think of all the information, knowledge, that's packed into those one trillion. And interestingly, this is now multimodal with language, with images, with speech....
Certain diseasesaffect only specific cells within the brain. For example, the symptoms ofmultiple sclerosisare caused by damage to the glial cells that manufacture and maintain the myelin sheath that insulates axons. Without this normal nerve covering, electrical transmission is compromised and symptoms...
Some patients reported numbness or tingling in their fingertips or lips on the side of treatment. This may be due to swelling (a normal response) of the treated area, also called the Vim of the thalamus, and is next to the area of the brain that affects sensations of the hands and face...
A contrast MRI is superior at measuring and evaluating tumors. Adding contrast makes it possible for the radiologist to detect even the smallest tumor and provides information about the precise location of the tumor. The radiologist can interpret an MRI contrast scan better, since they have more ...
With the help of radiological tools like MRI machines, X-rays, and CT scanners, AI can identify diseases such as tumors and ulcers in the early stages. For diseases like cancer, there is no solid treatment, but the risk of premature death can be greatly reduced if the tumor is detected ...
