The differential absorption of light by tissues also produces images that are weighted toward optical reporters and probes that are located closer to the surface of a subject.
Had someone weighted the 2008 electorate by 2004's, they would have produced a weighted sample that was weighted with the wrong assumptions.
Identify the numbers that are weighted.
In addition, grading discriminant classification functions, that are weighted combinations of image features, described below in the Analysis section, were assessed as prognostic factors.
They showed a hypointense signal on T1-weighted images that was slightly hyperintense relative to CSF, and a hyperintense signal on T2-weighted images that was either isointense or slightly hypointense relative to CSF.
Description of ROI margins (i.e., distance from tumour periphery) ROI shape and size (fixed or variable) Single or multiple slice ROI measurement Verification of ROI position on diffusion-weighted images that were used to calculate the ADC map T Tesla, EPI echo planar imaging, ECG electrocardiogram, ROI region of interest.
No abnormalities were observed on magnetic resonance image (MRI) of the brain, except for a high signal intensity on the T2-weighted images that was not significant.
The parameters for affine and nonlinear transformation into a template of T1-weighted images that was already fitted to a standard stereotaxic space (Montreal Neurological Institute [MNI] template) were estimated based on the high-resolution 3D T1-weighted MR images using the least-square means (Friston et al. 1995b).
The inclusion criteria were (1) referral for brain perfusion SPECT imaging for dementia screening, (2) no neurological or psychiatric symptoms, (3) HDS-R score >25, and (4) no detectable abnormalities visible on MRI examination of the brain, except for a high signal intensity on T2-weighted images that was not significant.
Microbleeds were defined as focal, nodular areas of signal loss in brain parenchyma on T2* images that are invisible or smaller on T2-weighted spin echo images [ 17].
The voxel is positioned to avoid blood vessels and the biliary tree, using T2-weighted HASTE transaxial images that are also acquired in the same phase of respiration.
