Modelling of hyperpolarized pyruvate to lactate conversion can be improved upon with consistent and reliable injections using an automated system. We have improved upon our previously designed injector by using a completely MR compatible direct drive peristaltic pump with a stepper motor and microcontroller. The new injector allows faster injections, no syringe filling, and arbitrary injection volumes. We show excellent correlation between demand and delivered volumes in the range 0.100-10.00ml and faster delivery of hyperpolarized pyruvate into a test phantom.
