Metabolite Mapping with Extended Brain Coverage Using a Fast Multisection MRSI Pulse Sequence and a Multichannel Coil
Figure 1
Pulse sequence diagram and timing for multi-section MRSI. The Tp is the time for the preparation period, which includes water suppression and outer volume suppression; τ 1 and τ 2 are the durations of 90° and 180° pulses, respectively; TE is the spin echo time; Td is the time delay before data acquisition, which is used for slice selection in the z-direction and phase encoding in the x-y plane of the slice (not shown); is the acquisition time; is the time for one slice, and the total repetition time TR for slices is . WS: water suppression; OVS: outer volume suppression; ACQ: acquisition.
