diffusion imaging造句

• Other investigators have attempted to build whole-brain connection matrices from diffusion imaging data.
• But tensor diffusion imaging will play a role in many more diseases, says NIH inventor Peter Basser.
• So if something blocks part of a nerve fiber, the new " tensor diffusion imaging " detects the resulting water changes, signaling damage.
• Diffusion imaging has gained importance in the past decade as a valuable means of depicting white matter injury caused by various disease processes.
• In addition, the study team will perform diffusion imaging on one to two human volunteers at each of four sites, in conjunction with phantom imaging.
• High angular resolution diffusion imaging ( HARDI ) addresses the well-known limitation of DTI, that is, DTI can only reveal one dominant fiber orientation at each location.
• Orientation distribution function ( ODF ) characterizes the angular profile of the diffusion probability density function of water molecules and can be reconstructed from High Angular Resolution Diffusion Imaging ( HARDI ).
• The second type of phantom, which will be provided by Walter Schneider, PhD at the University of Pittsburgh, will provide ground truth for other important diffusion imaging parameters, including fractional anisotropy and radial diffusivity.
• This study uses diffusion imaging phantoms to evaluate differences between scanners with the goal of providing acquisition techniques that will allow data to be compared across different patient groups and combined into large data collections.
• If diffusion imaging is to be developed as a means to evaluate Veterans with suspected TBI, a uniform type of image acquisition is needed across the different types of imaging systems available within the VA hospital network.
• Analysis of diffusion images showed that the visual word form area ( VWFA ) is connected to the occipital lobe via the inferior longitudinal fasciculus ( ILF ), a projection that runs between the temporal and occipital lobe.
• The world first diffusion images of the normal brain were made public in 1985 in London at the international SMRM meeting and the first diffusion images of the brain of patients were shown at the RSNA meeting in Chicago the same year ( then published in Radiology ).
• The world first diffusion images of the normal brain were made public in 1985 in London at the international SMRM meeting and the first diffusion images of the brain of patients were shown at the RSNA meeting in Chicago the same year ( then published in Radiology ).
• In fact, Duke physicians consider the new scans so useful that the North Carolina hospital is believed the first to give this " tensor diffusion imaging " to every person prescribed a standard brain MRI regardless of the reason _ resulting in a unique library of normal and abnormal brain anatomy.
• A variant of diffusion weighted imaging, "'diffusion spectrum imaging "'( DSI ), was used in deriving the Connectome data sets; DSI is a variant of diffusion-weighted imaging that is sensitive to intra-voxel heterogeneities in diffusion directions caused by crossing fiber tracts and thus allows more accurate mapping of axonal trajectories than other diffusion imaging approaches.
