sup][2] However, due to the complexity of skull base structure and
partial volume effect, it has difficulty localizing single or multiple leaks in complex and multiple skull base fractures.
10, 11] have recently used calibration curves incorporated with
partial volume correction algorithm by selecting manually a region covering the tissue around the internal carotid artery, which showed improved reproducibility of AIF determination.
Partial volume was calculated by interpolating the four QF CSAs in order to determine whether the most proximal image CSA was representative of the whole muscle.
As high resolution (HR) images produce high signal changes without
partial volume effect than the low resolution images8.
Mimics of the HMCA sign, the pseudo hyperdense MCA sign, include vascular calcification, raised haematocrit, intravenous contrast and
partial volume averaging.
We have used cubic splines throughout this paper, except in the cases that involve
partial volume, for which no explicit interpolation takes place.
Partial volume effect appears as "blurring" over sharp edges.
It also provides thinner slices with reduced
partial volume artifact and decreased noise as well as isotropic imaging with almost equal resolution in all planes.
The Vivace 3D imaging suite offers four distinct rendering modes for better image viewing - maximum intensity projection (MIP), minimum intensity projection (minIP), shaded volume and unshaded volume, as well as multi-planar reformatting (MPR), powerful tools for cross-correlation between volume rendered views, and MPR views and "opacity modulations" that eliminate artifacts from
partial volume effects.
A model was created supposing that all the NP8 injected mixed instantaneously with a
partial volume of the melt pool [ILLUSTRATION FOR FIGURE 12 OMITTED].
In addition, PPG's ability to successfully integrate recent acquisitions, combined with our recent earnings performance, has elevated our return on capital toward pre-recession levels despite only a
partial volume recovery on a much larger capital base," he said.
Under these conditions the hematocrit value as the
partial volume of erythrocytes in whole blood was lowered to about 10 percent.
