POLYMER, CONTRAST AGENT FOR NUCLEAR MAGNETIC RESONANCE ANALYSIS OR MAGNETIC RESONANCE IMAGING USING SAID POLYMER, COMPOUND, AND METHOD OF NUCLEAR MAGNETIC RESONANCE ANALYSIS AND METHOD OF MAGNETIC RESONANCE IMAGING USING SAID POLYMER

摘要

PROBLEM TO BE SOLVED: To provide a substance with high selectivity and high sensitivity as a substance used as a contrast agent for a method of nuclear magnetic resonance analysis or a method of magnetic resonance imaging.SOLUTION: When a polymer is used that has, in a side chain thereof, a sequence of aH-C-N,H-N-C, orH-C-C bond, which is a structure labeled with stable isotopesC andN, 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.
