Spin echo mr imaging

Abstract

MR imaging comprising the steps of: subjecting an object () to an imaging sequence of RF pulses and switched magnetic field gradients (GS, GP, GM), which imaging sequence is a steady state sequence comprising a plurality of repeatedly applied acquisition blocks (), wherein each acquisition block () comprises two units () in immediate succession, namely: i) a first unit () starting with an excitation RF pulse radiated toward the object (), with the duration of the first unit being an integer multiple of a given time interval T, and ii) a second unit () starting with a refocusing RF pulse radiated toward the object () and comprising a readout magnetic field gradient (GM) and a phase encoding magnetic field gradient (GP), with the duration of the second unit () being an integer multiple of the time interval T, acquiring one or more phase-encoded spin echo signals () in a sequence of acquisition blocks (), and reconstructing one or more MR images from the acquired spin echo signals (). Moreover, the invention relates to a MR device () and to a computer program for a MR device ().
