title: Double EPI sequence with 180 degrees RF pulses.
abstract: 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.
