The injector (100) comprises a protocol setting means (410) for setting the injection protocols of the contrast medium and the diluent, and a speed control means (440) for controlling the action of the piston drive mechanism (130) in accordance with the injection protocols. In the injection protocols the injection speed (VA) of the contrast medium is higher than the injection speed (VB) of the diluent when a time (T1) elapses after the injection start, the injection speed (VA) of the contrast medium monotonously decreases whereas the injection speed (VB) of the diluent monotonously increases for the period from the time (T1) to a time (T2), and the injection speed (VB) of the diluent is higher than the injection speed (VA) of the contrast medium when the time (T2) elapses. |
