Finally, in our group of patients with mild CAD with homogeneous myocardial perfusion in the majority of segments, MBF quantification with either Rb or O-water revealed significantly decreased MBF, MFR and CVR as compared to control subjects.
METHODS: Research testing of peripheral blood included immunoscope evaluation of T-cell receptor beta variable gene segment repertoire diversity, quantification of T-cell receptor rearrangement excision circles, and detection of naive T cells (expressing CD45RA and CD62L).
With this method, the circumferential distribution of the lipid plaques/FC was first identified by human analysts in all frames containing FC, then the FC boundaries in the radial dimensions were automatically segmented and volumetric quantification was performed on the segmented FC.
Degeneration, injury, and surgical interventions may alter the mechanical properties of spinal motion segments, but the quantification of these alterations in vivo is problematic.
Starting on Oct. 7, the second part of Phase Two--the quantification segment--begins.
Custom image segmenting software and quantification were implemented to ensure that the retinal thicknesses were calculated in the same manner for both the Cirrus and Heidelberg.
Standard segmentation and morphology quantification algorithms were applied as well as finite element (FE) simulation based on segmented and gray value images.
Computer-assisted continuous monitoring of the ST-segment allows detection and quantification of recurrent ischemia in patients with acute coronary syndromes.
Here an improved curvature quantification determined the distributions of segment frequency, segment lengths, angles between segments, frequency of inflection points, relative inflection point locations, and overall angle changes for each fringe for three soots and a carbon black.
We designed an automated quantification method to segment and extract 3D cell descriptors from osteocyte lacunae.
