WebAnisotropy tends to be shown either as a graph plotting resistance, reactance, or phase as a function of angle with respect to the direction of muscle fibers or as a ratio of transverse (perpendicular to fibers) measurement to longitudinal measurement (parallel to muscle fibers) of a given impedance factor. [20] WebDec 29, 2004 · Fractional anisotropy (FA) was measured in the internal capsule, and in the normal-appearing white matter (WM), adjacent to the lesion, and away from the lesion, at a set distance of 2–3 cm. In each patient, increased or decreased FA measurements were those that varied from mirror values using an arbitrary 10% threshold.
WebFeb 1, 1999 · Comparing well-watered to water-stressed roots (at 48 h) showed that water stress decreased retardation of the cell walls considerably (Fig. 7), despite the fact that throughout most of this region in water-stressed roots the radial expansion rate was decreased and expansion was more anisotropic. In other words, the walls of well … http://www.ajnr.org/content/22/3/456
