ABSTRACT:
A phantom for diagnosis by nuclear magnetic resonance imaging comprises a container made of a synthetic resin and a hydrogel sealingly contained in the container. The container has at least one opening into which a sample material is inserted. The hydrogel is prepared by charging an aqueous solution of a polyvinyl alcohol into the container, cooling the aqueous solution to minus 10.degree.C. or lower to obtain a cooled frozen mass and thawing the cooled frozen mass. Also disclosed is a method for determining resolution power or discrimination capacity of an NMR imaging apparatus.
