Real-time CMR. A Schematic diagram of real-time MRI fluoroscopy sequences for multi-planar interactive imaging. B Real-time bSSFP images with and without interactive saturation (“magnetization preparation”) pulses for gadolinium-filled balloon visualization from 1.5 T (MAGNETOM Aera, Siemens Healthcare, Erlangen Germany). Typical commercial real-time MRI parameters are 5–10 frames per second using bSSFP at 1.5 T (TE/TR = 1.3/2.6 ms, matrix = 192 × 144, acceleration factor = 2–4). bSSFP: balanced steady-state free precession
