B. An inverting RF pulse
C. Presaturation
D. Spoiling
E. CSF nulling ✔Correct Answer-D (spoiling - To reduce the steady state (T2*) effect, a technique
known as "spoiling" can be employed to allow for fast scans with T1 contrast. RF spoiling occurs
when additional RF pulses are used to "spoil away" the steady state effect (residual transverse
magnetization) before the next excitation, yielding T1 contrast for dynamic imaging of organs or CE
MRA sequences.)

A. T2* gradient echo
B. Steady-state gradient echo
C. Coherent gradient echo
D. Incoherent gradient echo ✔Correct Answer-D (Incoherent gradient echo -- Gradient echo
sequences requiring high signal from fluid are known as T2* gradient echo, Steady-state gradient
echo or coherent gradient echo. Incoherent gradient echo (or spoiled gradient echo) sequences yield
T1 contrast due to the removal of residual transverse magnetization before the next excitation.)
