This invention relates to the interdisciplinary field of biomedicine and molecular imaging, specifically a novel magnetic resonance imaging contrast agent, its preparation method, and its application. The contrast agent uses thymosin α1 as the parent compound, linked with three identical substituents R, where R are metal chelate groups. These metal chelate groups are formed by coordination of a chelating agent and a metal ion; the chelating agent can be diethylenetriaminepentaacetic acid, etc., and the metal ion can be selected from gadolinium, manganese, and iron. The preparation method of the contrast agent includes: activating the chelating agent and grafting it onto thymosin α1 to form a chelate precursor; and coordinating the chelate precursor with a metal ion. The contrast agent prepared by this invention exhibits a significant T1 enhancement effect, lymphoselectivity, and reduced concomitant venous contamination; detection results show that it has excellent lymphatic system visualization capabilities in in vivo animal imaging, providing a prospective reference for replacing existing contrast agents.
