which presently account for the majority of clinical brain MRI scans9. We focused on implementing and optimizing these four critical clinical protocols. T1W protocol used a 3D gradient-echo (GRE) sequence with TR/TE = 52/13 ms, while T2W and FLAIR protocols used a 3D fast spin echo (FSE...
MRI emits no radiation and has no known detrimental effects on the patient. It is a safe painless procedure. These scans provide clear, detailed images for a variety of pathology and soft tissue injures. Including but not exhaustive:Neurological Imaging: MRI head and ...
andintegratesthe X-ray data from the numerous scans to construct a detailed cross-sectional image of the brain. A series of such images enables physicians to locate brain tumors,cerebralabscesses,bloodclots, and other disorders that would be difficult to detect with conventional X-ray techniques....
Raichle, a collaborator in the NIH Human Connectome project, is one of the pioneers of "resting state" MRI, in which brain scans are taken of patients not involved in any specific task. He believes that the ongoing spontaneous activity discovered during such scans will tell us about how the ...
"There are MRI scans now that can detect brain atrophy even before people show symptoms of Alzheimer's disease," Yablonskiy said. "Our technique can show the brain degrading even before it begins to atrophy." The researchers are now working on applying their technique to brain diseases and ...
Structural MRI scans were preprocessed using the DARTEL Toolbox following standard procedures for VBM40 through the Statistical Parametric Mapping software (SPM12 (ref. 106)). Functional images were preprocessed using the Data Processing Assistant for Resting-State fMRI toolbox (v.4.4 (ref. 107)) ...
The MRI scans of the participants, showed that the high multitaskers had less brain density in theanterior(adj.前部的;靠前的;先前的;早先的)cingulate((adj.昆虫腹部)有色带环绕的)cortex. This is the brain region responsible for empathy and emotional control. ...

(MRI) scans (T1-weighted, contrasted with MultiHance®, 0.1 mmol kg−1of body weight) were obtained to plan safe electrodes trajectories that avoided vascular structures preoperatively. Postoperative Computed Tomography (CT) scans were obtained and coregistered with preoperative MRI scans to ...
Using a new kind of MRI measurement, neuroscientists reported higher levels ofoxidative stressin patients withschizophrenia, when compared both to healthy individuals and those with bipolar disorder. "Intensive energy demands on brain cells leads to accumulation of highlyreactive oxygen species, such as ...
