Fabrication advances in nanotechnology have recently enabled construction of nanostructured materials with macroscopic dimensions and interesting electrical properties. A macroscopic sheet composed of carbon nanotubes was used to construct an MR receiver coil. The electrically conducting nanomaterial is made by a solid-state process akin to textile drawing. It displays negligible electrical skin effects over the range of frequencies relevant to MR imaging. The receiver coil was used to image a mouse head at 3T at 0.25 mm in-plane resolution and resulted in excellent image quality. The material offers the possibility of significant enhancements in SNR in clinical MR imaging applications.
