MRI CONTRAST MEDIUM AND DIAGNOSTIC METHOD.

摘要

An MRI contrast medium (suspension) comprising an oily fatty acid, fatty acid ester or perfluorinated compound and a particulate paramagnetic compound contained therein. It can be used stably for long and can be administered to a target region, whereby its dose can be reduced. In conducting diagnosis, it can be held in a target region stably for long, so that it makes monitoring by MRI possible and can dispense with X-ray CT, thus being free from the problem of radiation exposure.
