There is provided a contrast agent for diagnosis of vascular disease containing a gadolinium-based compound as an active ingredient. It has been found that the gadolinium-based compound Gd-DOTA-click-SF of the present disclosure, has a higher molar longitudinal relaxivity (r

) than Dotarem, is stable, and does not affect in vitro cell viability. In addition, it has been found through MRI images that the specific binding of Gd-DOTA-click-SF in an animal model of abdominal aortic aneurysm established using elastase, a serine protease, is remarkable. Also, it has been confirmed that the content of the gadolinium-based compound of the present disclosure that binds to serine protease in the aorta, that is, the content of gadolinium in the aorta, is remarkable. Thus, the Gd-DOTA-click-SF compound according to the present disclosure may be usefully used in MRI and CT imaging diagnosis for vascular disease.
