Delivering a contrast (or therapeutic) agent to a subject inside an MRI bore requires an expensive electronically programmed syringe pump and a long tube filled with the agent. We developed an inexpensive 3D-printed MRI-compatible syringe pump that can be used inside an MRI bore. This syringe pump yields a highly reproducible infusion rate, which can be readily adjusted using gears with different gear ratios.
