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...
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....
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 ...
What is a brain lesion? A brain lesion describes damage or destruction to any part of the brain. It may be due to trauma or any other disease that can cause inflammation, malfunction, or destruction of brain cells or brain tissue. A lesion may be localized to one part of the brain, or...
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 ...
Postural or orthostatic hypotension as a cause of dizziness In individuals who are dehydrated or anemic, blood pressure readings may be normal when they are lying flat; however, the lack of fluid is unmasked when they stand up quickly. The lack of blood in the brain may cause dizziness and ...
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 ...
