Double EPI sequence with 180 degrees RF pulses.
Rapid imaging can be performed in the magnetic field of low homogeneity using 180 degrees RF pulses instead of gradient reversals to form a series of differently phase-encoded echoes. A modified version of pi-pulsed EPI which samples the data in two complementary shots was designed. Its advantage for objects of short T2 is illustrated by phantom images.
