1. An injection system for use with a magnetic resonance imaging (MRI) system, said MRI system having a room and a window therewith shielded from electromagnetic interference, said injection system comprising:

  • (a) a system controller external to said room;

    (b) an injection apparatus within said room, said injection apparatus including a base assembly, a head assembly and a rigid tubular casing for supporting said head assembly above said base assembly and for housing a flexible drive shaft, said base assembly including a motor control circuitry and an electric drive motor controlled thereby operably linked to one end of said flexible drive shaft, said head assembly including an injector and a drive mechanism therefor operably linked to an other end of said flexible drive shaft; and

    (c) a communications control link, substantially non-reactive with a magnetic field produced by said MRI system, between said system controller and said injection apparatus thereby enabling said system controller to operably control said base assembly and said head assembly therewith for controlling the injection of fluid into a patient from a syringe mounted to said injector during a magnetic resonance imaging procedure.
