TI  - Visualization and tracking of a conventional guidewire with low flip angle SSFP imaging: an initial study
AV  - none
N2  - Inductive coupling between signal reception coils and conventional guidewires in the presence of low flip-angle (LF) balanced SSFP (b-SSFP) imaging may permit the visualization of guidewires with positive contrast. To test our hypothesis, ex-vivo and in-vivo experiments were performed using a radio-opaque coronary guidewire and LF b-SSFP imaging. Our initial studies showed that it is possible to visualize and track a conventional guidewire with positive contrast using LF b-SSFP imaging within ex-vivo and in-vivo settings. These results lend support to the hypothesis that signal reception coils and passive guidewires may be inductively coupled in the presence of LF excitations.
