Figure 3From: Dual echo positive contrast bSSFP for real-time visualization of passive devices duringmagnetic resonance guided cardiovascular catheterizationIn vivo positive contrast from a range of dephasing moments. Modified slice refocusing moments (25% to -100% of full refocusing moment) generating positive contrast signal from the guidewire in vivo. A refocusing moment of -50% was chosen for our application.Back to article page
