    • PROBLEM TO BE SOLVED: To provide a system and a method for a targeting magnetic resonance imaging of vascular system which are cost-effective and safe and identify the presence, position, and size of a CVD (celebrovascular disease) target in a vascular system correctly by using a simple method. SOLUTION: A method to decide presence or absence of a static target in the vascular system of a mammal comprises (a) a process to administer a targeting MRI (magnetic resonance imaging) contrast agent to this mammal, (b) a process to acquire a first MRI data set including an image of this vascular system, and (c) a process to acquire a second MRI data set. This targeting MRI contrast agent has a specific affinity for this static target, and furthermore, this targeting MRI contrast agent can provide contrast enhancement of the vascular system of this static target and this mammal. This second MRI data set comprises a process to be acquired in suitable hours in order to provide contrast enhancement of this static target at an observable level for the reinforcement of blood and tissue of a background when this static target is present.
