The purpose of this work was to present the cinglulum bundle located above the corpus callosum. It consists of a complex white matter fiber tract of the human brain that comprises long association fibers, commissural fibers, and various U-fibers. The fiber tractography was achieved by diffusion tensor imaging using a single-shot STEAM-sequence with 24 gradient directions at 1.8 mm isotropic resolution. In order to map the full cingulum bundle 41 oblique sections in AC-PC orientation were acquired without gaps in an interleaved order.
