Outline of Final Research Achievements

Even though it is frequently cited that Japan has the highest number of MRIs per person, we rarely find studies evaluated those utilities and installations. This study aims to survey MRI installation and utilities in Japan. We mailed questionnaire to 5,437 facilities have MRI(s) and we received 2,272 responses (41.8% response rate). Questions include the type of facility, the detail information about their installed MRI, and their utilization such as operation rate per day, target of scans, scan protocol, staffing, etc. From a statistical analysis of the collected data, many of the clinics and the hospitals with a small number of beds did not have a full-time radiologist or a radiographer. This data will be effective for future discussion of MRI installation in Japan.
