We developed a new noninvasive technique to visualize the anatomical structure of the nerve fiber system in vivo, and named this technique magnetic resonance (MR) tractography and the acquired image an MR tractogram. MR tractography has two steps. One is to obtain diffusion-weighted images sensitized along axes appropriate for depicting the intended nerve(More)
We investigated application of the OS-EM method to the (123)I-IMP ARG method to measure regional cerebral blood flow (rCBF). First, scan time and subsets were fixed at 20 min and 16, respectively, and the influence of iteration on the CCF and quantitative rCBF values obtained by the ARG method was investigated when the iteration number was set at 2, 4, 8,(More)
