Versatile MRI acquisition and processing protocol for population-based neuroimaging A neuroimaging protocol presenting versatile high-resolution and time-efficient MRI acquisition and processing strategies suitable for large-scale and long-term population studies, which include structural, diffusion-weighted and...
As a key oscillatory activity in the brain, thalamic spindle activities are long believed to support memory consolidation. However, their propagation characteristics and causal actions at systems level remain unclear. Using functional MRI (fMRI) and electrophysiology recordings in male rats, we found th...
Whole-brain anatomical connectivity in living humans can be modeled as a network with diffusion-MRI and tractography. Network nodes are associated with dis... A Zalesky,A Fornito,IH Harding,... - 《Neuroimage》 被引量: 1417发表: 2010年 Sex differences in the adolescent brain Adolescence is ...
All MRI images are resized to a standard dimension to ensure uniformity in input size for the model. This is essential because convolutional neural networks (CNNs) require a fixed input size. Rescaling the pixel values to a range of 0 to 1 assists in stabilizing the training process as it ...
Brain images are primarily compatible with MRI; however, CT and PET are also considered. It can be observed from the proposed review that researchers are more oriented toward the brain parts of oncology study with 45% as compared to other anatomical features of the human body. The remaining ...
Each patient was scanned using a 3.0 T magnetic resonance imaging (MRI) instrument to locate the STN target. On the day of the surgery, all patients were positioned in a stereotactic frame (Leksell G type) under local anesthesia to perform computed tomography (CT) scanning. After fusing the ...

Once on the MRI scanner, a piece of equipment called a coil will be placed around the affected area and the scan will commence. The examination is completely painless.How long does an MRI Scan take?The total scan time is usually 20 minutes per body area. We rec...
Standard MRI: this machine looks like a long cylinder with a narrow tube in the center. You lay on a moveable bed and your whole body slides inside the tube. Even though this machine can be confining to some people, it produces the best-looking images. Short-bore MRI: this machine is ...
Nevertheless, DCE-MRI is not routinely used in cSVD studies due to practical impediments (long scan time, exogenous contrast), lack of widespread expertise, and technical and physiological complexities and confounds [100], [101]. There are few studies of BBB permeability change over time in ...
