An MRI-compatible catheter includes an elongated flexible shaft having opposite distal and proximal end portions. A handle is attached to the proximal end portion and includes an actuator in communication with the shaft distal end portion that is configured to articulate the shaft distal end portion. The distal end portion of the shaft may include an ablation tip and includes at least one RF tracking coil positioned adjacent the ablation tip that is electrically connected to an MRI scanner. The at least one RF tracking coil is electrically connected to a circuit that reduces coupling when the at least one RF tracking coil is exposed to an MRI environment. Each RF tracking coil is a 1-10 turn solenoid coil, and has a length along the longitudinal direction of the catheter of between about 0.25 mm and about 4 mm.
