1. A syringe retaining member protruding radially outward relative to an outer surface of a sidewall of a barrel of a syringe, the syringe retaining member comprising:
a base surface extending perpendicular to a longitudinal axis of the syringe, wherein the base surface is configured for releasably engaging a locking surface of a locking mechanism of a syringe port of a fluid injector;
a third surface tapered axially relative to the longitudinal axis of the syringe;
a first surface extending from a first end of the base surface to a most proximal end of the third surface; and
a second surface extending from a second end of the base surface to a most distal end of the third surface,
wherein at least a portion of the third surface axially ejects the syringe from the syringe port upon rotation of the syringe.
