Bilateral, symmetric, and multifocal areas of consolidation, often associated with groundglass opacities, are the predominant radiographic findings in pediatric patients with a more severe clinical course of S-OIV infection. (C)RSNA, 2009″
“We report the substrate-modified magnetic properties of the CuAu type-I (L1(0)) structure of Mn(x)Ga (1.2 < x < 1.5) films. The magnetic properties Adriamycin mouse of the MnGa films differed greatly due to the influence of the substrate. The MnGa film
is a hard ferrimagnet when grown on GaSb (111), becomes a soft ferrimagnet when grown on Al(2)O(3) (0001), and exhibits an absence of a net magnetic moment when stabilized on a GaSb (100) substrate. This difference was attributed to the substrate, which forces MnGa film to be two-dimensionally stabilized in a different orientation and thus leads to the modified crystal symmetry and a change in the magnetic property. The results may be helpful for forming a comprehensive understanding of MnGa and for finding new applications in spintronic devices. (c) 2010 American Institute of Physics. [doi: 10.1063/1.3517083]“
“Purpose: To perform in vivo imaging of the cerebellum with an in-plane
resolution of 120 mm to observe its cortical granular and molecular layers by taking advantage of the high signal-to-noise ratio and the increased magnetic susceptibility-related contrast available at high magnetic field strength such as 7 T.
Materials and Methods:
The study was approved by the institutional review board, DMXAA solubility dmso and all patients provided written consent. MDV3100 mw Three healthy persons (two men, one woman; mean age, 30 years; age range, 28-31 years) underwent MR imaging with a 7-T system. Gradient-echo images (repetition time msec/echo time msec, 1000/25) of the human cerebellum were acquired with a nominal in-plane resolution of approximately 120 m m and a section thickness of 1 mm.
Results: Structures with dimensions as small as 240 m m, such as the granular and molecular layers in the cerebellar cortex, were detected in vivo. The detection of these structures was confirmed by comparing the contrast obtained on T2*-weighted and phase images with that obtained on images of rat cerebellum acquired at 14 T with 30 m m in-plane resolution.
Conclusion: In vivo cerebellar imaging at near-microscopic resolution is feasible at 7 T. Such detailed observation of an anatomic area that can be affected by a number of neurologic and psychiatric diseases, such as stroke, tumors, autism, and schizophrenia, could potentially provide newer markers for diagnosis and follow-up in patients with such pathologic conditions.
