Q

What type of pulse sequence uses a 90° excitation pulse followed by one or more 180° rephasing pulses?

a. conventional spin echo
b. coherent gradient echo pulse
c. inversion recovery
d. steady state free precession

A

a. conventional spin echo

IR has a 180° pulse before the 90° pulse then in followed by one or more rephasing pulses
