bSSFP artifact
• Balanced Steady State Free Precession
also known as:
– bTFE, bFFE (Philips) – trueFISP (Siemens) – FIESTA (GE)
• Steady state depends on T 1 and T 2 • Spins from many excitations create a steady state of precessing spins • B0 distortions (susceptibility) result in spins that are off-resonance and don’t see the RF pulses. Thus they don’t produce a signal
