[Collection of information regarding implants, internal and external metallic objects for MRI examinations]

In Japan, various types of MRI equipment, having varying magnetic field strengths, are widely used. However, the biggest problem encountered while utilizing an MRI is the scarcity of information and guidelines pertaining to implants, internal, and external metallic objects. This leads to uncertainty when an unspecified object is encountered during an examination andcreates the possibility of performing an ambiguous MRI. Therefore, this study classified a range of objects into 12 categories using database management software. An attempt was made to create an environment where reference and comparison of products could be performed. This study also investigated the ways and extent to which medical equipment package inserts reference the MRI. With the co-operation of various corporations and the use of information such as medical equipment package inserts, product information was collected and an environment for the reference and comparison of products became available. In addition, it became apparent while examining these package inserts that orthopedic products had the least information available. It is likely that this information will be useful in medical settings and this kind of database will become increasingly necessary in the future.
