A syringe includes a cylindrical body having a distal end and a proximal end, an injection section at the distal end and an expansion section at the proximal end, the injection section and the expansion section being connected by a cylindrical center section of relatively uniform outer diameter. The injection section includes a conical portion and an injection neck, the conical portion including an alignment flange extending outward from at least a portion of the conical portion. The syringe further includes a plunger movably received in the body and having a coupling end with a pair of flexible coupling members defining a slot therebetween for engaging a drive piston of an injector, the slot being substantially aligned with the alignment flange such that the alignment flange provides an indication of the orientation of the slot, the plunger seated for storage in the expansion section. A syringe has a reduced wall thickness at the expansion section such that an inner diameter of the expansion section is larger than the inner diameter of the center section for allowing the expansion section to expand under radial outward force exerted by the plunger.
