摘要:
In a method and magnetic resonance (MR) apparatus for acquisition of MR data from a slice in a subject, a first slice selection gradient is activated in a first direction perpendicular to the slice, and an RF excitation pulse then selectively excites nuclear spins in the slice. A second slice selection gradient is activated along the first direction, and a refocusing pulse is radiated. A first phase encoding gradient along the first direction is activated, and a second phase encoding gradient is activated along a second direction perpendicular to the first direction. A selection gradient is activated along a third direction perpendicularly to the first and second directions, during which MR data are acquired from the slice. The acquired MR data are entered into multiple k-space lines that are selected starting from the refocusing pulse, without a further RF pulse being radiated.
