The heated injection syringe (30) is used for injecting liquid contrast agents into blood vessels of living bodies, and it comprises a barrel (10) with a piston (20) movable to and fro therein, and a heating device (35) surrounding the barrel in a contact-making manner. The heating device (35) which is designed as an integral component comprises an insulating foil (42), a heating element (41), an insulating jacket (40) and at least one thermocouple (45). For control of the heating temperature, the thermocouple transmits a locally temperature-dependent signal to an electronic member (51). Exact equalisation of the temperature gradient between the ambient temperature and the temperature of the contrast agent, on the one hand, and between the ambient temperature and the temperature at the site of the thermocouple, on the other hand, is achieved by means of the thermocouple (45) arranged a short distance (43) away from the heating element (41). <IMAGE>
