Clinical applications of the superconducting MRI system were started in April of 1985 in our hospital. We had performed examinations of 575 cases for seven months at a field strength of 0.35T. In April of 1985 clinical studies using the 1.5T MRI system were started. Spatial resolution as much as X-ray CT was possible by the superconducting MRI system. It is thus very effective for the treatment of central nervous system, pelvis and extremity, disorders since it is hardly in fluenced by motion artifacts. In thoracic and abdominal regions spatial resolution by MRI was inferior to that by X-ray CT, but its high contrast resolution and ability to provide optional plane images show it highly useful for clinical diagnosis and therapeutic plan therapy. By 1.5T MRI system the spectroscopy of P-31 is possible as well as high resolutional MR imaging for high signal to noise ratio. Many problems, remain to be solved, such as those of motion artifacts and chemical shift artifacts.
