4. You are imaging a liver and need to cover a volume of 19.2 cm x 19.2 cm x 10 cm at a resolution of 1 mm in all directions. Compare

the minimum total acquisition time and the SNR for a 2D GE sequence and a 3D GE sequence, assuming all other parameters are constant. Name at least one reasonable factor that might lead you to choose one sequence over another other than time and SNR.
