<p>PURPOSE:To enable the obtaining a clear image at a complicated part with rapid current of blood such as heart, liver and the like by performing an NMR diagnosis through a molded sheet made of a water absorbing resin having a specified structure. CONSTITUTION:A water absorbing resin composing a molded sheet is formed from a single gel and molecular chains of the water absorbing resin are entangled mutually. Water absorbed into the water absorbing resin is bonded chemically and/or physically to the resin to be dispersed evenly. To obtain such a water absorbing resin molded body, a mixture of an aqueous solution containing acrylic acid and/or acrylate alkali metal salt and a crosslinking agent and a optical initiator is coagulated to mold and irradiated with ultraviolet rays. The molded sheet thus obtained is applied on an affected part to perform an NMR diagnosis. This method enables the obtaining of a clear NMR images even in the heart, liver and the like.</p> |
