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. date: 2009 date_type: submitted event_title: 17th Meeting of the international society for magnetic resonance in medicine event_location: Honolulu, Hawaii event_dates: 18-24 April 2009 event_type: conference refereed: TRUE related_url_url: http://www.ismrm.org/09/index.htm related_url_type: org citation: Dharmakumar, Rohan and Koktzoglou, Ioannis and Tsaftaris, Sotirios A. and Zuehlsdorff, Sven and Tang, Richard and Graham, Wright and Li, Debiao Visualization and tracking of a conventional guidewire with low flip angle SSFP imaging: an initial study.
