Abstract

A drug solution injector (100) having a syringe packed with a contrast medium for taking a CT image of a subject with a CT system (300), by which the contrast medium is injected into the vessel of the subject by operating the syringe and which is provided with a leakage determination unit (122) for determining whether or not the contrast medium having been injected from the syringe leaks from the vessel of the subject using the CT data measured by the CT system (300).
