Which is NOT a common parallel imaging artifact?

Which option below would increase my SNR?

Susceptibility artifacts are most prominent in:

What artifact occurs when adjacent slices receive RF energy from neighboring pulses?

What imaging technique can separate fat and water using phase shifts?

Chemical shift occurs due to:

How does gradient moment re-phasing correct phase shifts  moving nuclei?

What does gradient moment rephasing correct?

What technique uses an RF pulse at fat’s resonance frequency to null its signal?

Chemical shift artifact appears in which direction on standard images?
