Research Abstract

We developed a magnetic resonance microscope by using high magnetic field of 14.1 T. We visualized chemically-fixed medaka in 20 μm isovoxel three dimensionally, where field gradients of 4.0 T/m at maximum were applied. Comparing 3D MRimages of p53 cancer suppressor gene mutant medaka with those of wild type medaka, differences in internal organs were obtained. In addition to that, we analyzed digitized effects in quantitative susceptibility mapping, which gave us a tissue iron contentmap and could be used for detecting local iron accumulation in a brain of a Parkinson’s disease patient.
