Chost artifact reduction in fact spin echo MRI sequences

摘要

In order to reduce ghosts due to increasing echo intensity fall-off in the course of an echo train in MR imaging employing the FSE method, the present method assigns individual echoes in the echo train to respective segments to acquire data F (S1 - S3), then assigns individual echoes arranged in the reverse order to the respective segments so that the order of signal intensity magnitude in the data F is inverted, to acquire data R (54. S5), adds the data F and R for each view, and produces an image from the sum data. The number of echoes in the echo train is preferably selected to be an even number.
