Abstract
A coil tuned to 21.3 MHz was incorporated into a nasogastric tube and used
as a marker of tube position during magnetic resonance (MR) imaging in a 0.
5-T scanner. Catheter tracking was investigated with the coil used in both
transmit/receive and in receive-only modes. Data acquired from this coil we
re overlaid on images obtained using the body coil of the scanner. Visualiz
ation of the full length of the catheter with local high signal at the tip
was achieved with a temporal resolution of approximately 1 second. (C) 2001
