摘要
Disclosed is a guide catheter that includes one or more RF antennas to enhance the visibility of the guide catheter in MR imagery. One embodiment of the guide catheter includes a loop coil at the distal end of the guide catheter and a loopless antenna between the distal end and the proximal end. By combinong a loop coil and a loopless antenna on the catheter, the shaft of the catheter may be visible in MR imagery while the distal end may appear in the MR imagery more brightly than the shaft.
