Metabolite Mapping with Extended Brain Coverage Using a Fast Multisection MRSI Pulse Sequence and a Multichannel Coil

Table 2

Comparisons of signal amplitudes acquired on a human subject with or without spacing between slices. Means and SD were calculated using (2). n is the number of selected voxels in the 4th slice. The TR was 2.3 s for tests 1 and 2, and 3.0 s for test 3.

Test	NAA; (mean ± SD)	Cr; (mean ± SD)	Cho; (mean ± SD)
1 (𝑛=34)	2.50%±4.47%	7.30%±4.09%	2.94%±9.71%
2 (𝑛=35)	7.33%±4.24%	1.56%±6.23%	5.63%±6.64%
3 (𝑛=38)	2.80%±5.95%	3.04%±8.07%	2.52%±10.0%
