An imaging suite, comprising: a magnetic resonance imaging system comprising an imaging bore; a fluid-driven injector comprising a fluid delivery device, a flexible fluid conduit and a non-ferrous and non-magnetic fluid drive, wherein the fluid drive is configured to not interfere with magnetic resonance imaging; at least one pump; a plurality of fluid conduits (138, 140, 142, 144) coupled to the at least one pump; a working fluid, wherein the at least one pump provides the working fluid to the fluid drive through the plurality of fluid conduits; and, a wall with shielding, wherein the at least one pump and the fluid-driven injector are disposed on opposite sides of the wall; characterised in that: the fluid-driven injector is disposed within the imaging bore; the fluid drive is responsive to pressure of the working fluid to impart a sequence of separate and discrete forces to drive the delivery device to flow medical fluid from the injector, wherein the fluid drive is configured to sequentially squeeze the flexible fluid conduit, wherein the fluid drive comprises: a cylinder block comprising a plurality of cylinders (114, 116, 118, 120), each cylinder being coupled to a respective fluid conduit of the plurality of fluid conduits (138, 140, 142, 144); a plurality of pistons (124, 126, 128, 130) disposed in series along the flexible fluid conduit, each piston being disposed within a respective cylinder of the plurality of cylinders; a separate valve for each cylinder (114, 116, 118, 120), wherein each of the valves is located between its respective cylinder and the at least one pump; and a control coupled to the at least one pump, the control and the fluid drive being disposed on opposite sides of the wall, wherein the at least one pump intakes and delivers the working fluid in response to at least one control signal from the control, wherein in response to the at least one control signal the at least one fluid pump and the valves cooperate to supply the working fluid in sequential pulses, one after another, to the cylinders, thereby causing the pistons to move sequentially and sequentially compress the flexible fluid conduit, to in turn impart the sequence of forces at different times and axial positions along the flexible fluid conduit. a magnetic resonance imaging system comprising an imaging bore;
