FIGURE 7

MRI‐guided right heart catheterization at 0.55T. Due to device heating, this nitinol guidewire with a gadolinium filled balloon tip catheter could not be used in a 1.5T scanner, but can be safely used for 0.55T MRI‐guided procedures. The gadolinium filled balloon is used to navigate the guidewire during right heart catheterization. Images acquisitions are real‐time bSSFP with partial saturation pre‐pulse (TE = 2 msec, TR = 4 msec, flip angle = 45°, partial saturation pre‐pulse flip angle = 60°).
