CMR of the NHLBI passive guidewire in vivo. The effect of various imaging sequences on in vivo guidewire conspicuity is illustrated. a During bSSFP CMR the iron-oxide susceptibility markers are conspicuous as the guidewire is advanced retrograde through the descending thoracic aorta. The signal-to-noise ratio is higher for images acquired using bSSFP [TR/TE, 2.88 ms/1.44 ms] compared with (b) GRE sequences with similar TE [TR/TE, 4.87 ms/2.18 ms]
