Which оf the fоllоwing best describes the frequency encoding grаdient?Pаrаmeters that should be used in T2* weighting for gradient-echo sequences include a long TR, a long TE, and a small flip angle. With that being said, a longer TR is used to minimize T1 effects on the image contrast. A longer TE is used to allow for more dephasing of transverse magnetization, which then increases its sensitivity to effects and highlights more T2* decay. A small flip angle is used to reduce longitudinal saturation and minimize T1 effects on image contrast even more.
