Abstract
As a substance used as a contrast agent for a method of nuclear magnetic resonance analysis or a method of magnetic resonance imaging, a substance with high selectivity and high sensitivity was demanded. According to the present invention, when a polymer having, in a side chain thereof, a sequence of aH—C—N,H—N—C orH—C—C bond, that is, a structure labeled with stable isotopes ofC andN, is used, the abundance of such a sequence in one molecule can be increased, and hence, high selectivity and higher sensitivity can be attained when used as a contrast agent.
