vGRASE: separating phase and T(2) modulations in 2D.
A new fast imaging technique, vGRASE, was designed and implemented on a clinical imager. In the vGRASE scheme, the T(2) modulation ghost, which is the main problem of the GRASE sequence, can be reduced by separating the phase and T(2) modulations in two encoding directions. Although it is not much faster than the original GRASE, vGRASE has much improved image quality, with the same advantages over RARE and EPI as the original GRASE.
