磁共振（MR）显微镜高达1-5 μ m的分辨率以前已经报道。然而，受试体模结构的宽度比报告的分辨率大一个数量级，e。例如，在一个实施例中，几十微米直径或壁厚的球形珠或毛细管已经被成像。在这项研究中，我们制造的结构具有几个微米的硅晶片上的宽度，并使用我们的1 μ m分辨率的MR显微镜在14.1 T成像。微米级的宽度结构，第一次，解决了MR显微镜。(C)2009爱思唯尔公司All rights reserved.
Magnetic resonance (MR) microscopy of up to 1-5-mu m resolutions have been reported previously. The tested phantom structures, however, had widths one order of magnitude bigger than the reported resolutions, e. g., spherical beads or capillary tubes of tens-of-micron diameters or wall thicknesses have been imaged. In this study, we fabricated structures having a few micron widths on a silicon wafer and imaged them using our 1-mu m-resolution MR microscopy at 14.1 T. Micron scale width structures were, for the first time, resolved by MR microscopy. (C) 2009 Elsevier Inc. All rights reserved.
