Question

Steady-state gradient echo sequences are classified according to whether the residual transverse magnetization Mxy is kept in phase (coherent steady state) or spoiled out-of-phase (incoherent or spoiled steady state).

A. True
B. False

Answer 1

Steady-state gradient echo sequences can be classified as coherent or incoherent based on the of the transverse magnetization. the statement in the question is True.

Step-by-step explanation:

Steady-state gradient echo sequences are classified according to whether the residual transverse magnetization Mxy is kept in phase (coherent steady state) or spoiled out-of-phase (incoherent or spoiled steady state).

Coherent steady state refers to the situation where the transverse magnetization is kept in phase. This means that the magnetization maintains a constant phase difference and has the same frequency. In contrast, incoherent or spoiled steady state refers to the situation where the transverse magnetization is out-of-phase or has random phase relationships. Therefore, the statement in the question is True.
