The understanding of the human brain is one of the main scientific challenges of the twenty-first century: Unravel the biological mechanisms of our mental life; Replicate cerebral functional features in artificial systems; Understand neurological or psychiatric diseases to allow early diagnosis and ...
MRI of the brain, adapted from Source, used under the Creative Commons License. 3T vs 1.5T MRI Speed A 3T MRI machine can create high-resolution images faster than a 1.5T system7. Faster imaging means less time inside the scanner, making the scan more comfortable. In addition, a shorter...
There are also three gradient magnets inside the MRI machine. These magnets are much lower strength compared to the main magnetic field; they may range in strength from 180 gauss to 270 gauss. While the main magnet creates an intense, stable magnetic field around the patient, the gradient magn...
Max Wintermark, M.D., professor of radiology and chief of neuroradiology, Stanford Hospital and Clinics, discussed MRI contrast safety issues at RSNA 2017. Read the article “FDA: No Harm in MRI Gadolinium Retention in the Brain,” and “European Medicines Agency Issues Update on Gadolinium Con...
The technologist will offer earplugs — MRI machines are noisy — or headphones and help you onto the table for your scan. (At ezra, we will play your favorite Spotify playlists to help you relax.) Depending on whether contrast is used, you can expect your scan to take as much as an ...
Fluid signal in the mastoid can be an incidental finding on T2-weighted magnetic resonance imaging and often is interpreted as mastoiditis by radiologists. This study examines 28 consecutive cases of such erroneously diagnosed "mastoiditis" and documents the presence or absence of otologic symptoms and...

fully utilized and even though it is at full capacity being used, it suffers from a problem of information overload. There's far too much in the environment than it can fully process. So to solve this problem of overload, evolution devised a solution, which is the brain's attention ...
And so in those cases, if I've got the main idea from the book or if it's just not capturing my interest very much, often I would just blitz through the rest of the book.所以在这种情况下，如果我获取了书中主要的想法，或者如果它没有引起我的兴趣，通常我会快速浏览这本书的其余部分。Yes...
A PET scan can pick up potentially cancerous areas or other abnormalities as these will use glucose at a much faster rate compared to normal cells. It may pick up abnormal changes in the body before an MRI or CT detects them due to the changes being at a cellular level. However, in so...
