Diffusional anisotropy of human brain was investigated clinically in six adult volunteers, eight premature neonates, and three infants aged 5-10 months. Diffusion-weighted magnetic resonance imaging was performed with gradient b of 450 sec/mm2. The direction of diffusion-sensitive gradients was changed among x, y, and z axes according to the orientation of(More)
Technical aspects of fast, ultra-fast MR imaging are described. Firstly, mechanism of steady state MR signals, generated by rf pulses with short repetition times, are focused, and described that the steady state signal contains echo signals that have different history. Imaging pulse sequence utilizing the steady state signals is referred to as Gradient(More)
