001) or dynamic contrast- enhanced and T2-weighted (P = .001) imaging; T2-weighted imaging combined with fused T2-weighted and DW imaging also was better than dynamic contrast- enhanced and T2-weighted imaging (P < .001). Tumor apparent diffusion coefficients were 0.60-1.32 x 10(-3) mm(2)/sec (median, 0.75 x 10(-3) mm(2)/sec), with no significant correlation with the depth of myometrial invasion (P = .31, r = -0.15).
Conclusion: Fused T2-weighted Bcl-2 inhibitor and high-b-value DW images at 3 T can
provide accurate information for preoperative evaluation of myometrial invasion. (c) RSNA, 2009″
“The existence of nonlinear objects of the vortex type in two-dimensional magnetic systems presents itself as one of the most promising candidates for the construction CH5183284 datasheet of nanodevices, useful for storing data, and for the construction of reading and writing magnetic heads. The vortex appears as the ground state of a magnetic nanodisk whose magnetic moments interact via the dipole-dipole potential D Sigma[(S) over right arrow (i).(S) over right arrow (j)-3((S) over right arrow (i).(r) over cap (ij))]/r(ij)(3)
and the exchange interaction (-J Sigma(S) over right arrow (i).(S) over right arrow (j))(.) In this work it is investigated the conditions for the formation of vortices in nanodisks in triangular, square, and hexagonal lattices as a function of the size of the lattice and of the strength of the dipole interaction D. Our results show that there is a “”transition”" line separating the vortex state from a capacitorlike state. This line has a finite size scaling form depending on the size, L, of the system as D(c)=D(0) +1/A(1+BL(2)). This behavior is obeyed by the three types of lattices.
Inside the vortex phase it is possible to identify two types of vortices separated by a constant, selleck kinase inhibitor D=D(c), line: An in-plane and an out-of-plane vortex. We observed that the out-of-plane phase does not appear for the triangular lattice. In a two layer system the extra layer of dipoles works as an effective out-of-plane anisotropy inducing a large S(z) component at the center of the vortex. Also, we analyzed the mechanism for switching the out-of-plane vortex component. Contrary to some reported results, we found evidences that the mechanism is not a creation-annihilation vortex anti-vortex process. (C) 2010 American Institute of Physics. [doi:10.1063/1.3318605]“
“Purpose: To retrospectively evaluate whether the enhancement patterns of pathologically proved clear cell, papillary, and chromophobe renal cell carcinomas (RCCs) measured on clinical dynamic contrast agent-enhanced magnetic resonance (MR) images permit accurate diagnosis of RCC subtype.
