Sixteen healthy dogs (12 males, 4 females; age 6.19\u00a0\u00b1\u00a02.17 years; weight 23.43\u00a0\u00b1\u00a09.65\u00a0kg) underwent\n 1<\/jats:sup>\n H\u2010MRS using both coil types with identical protocols. Multivoxel point\u2010resolved spectroscopy was performed on bilateral thalamic regions at short (TE\u00a0=\u00a030\u00a0ms) and long (TE\u00a0=\u00a0135\u00a0ms) echo times.\n N<\/jats:italic>\n \u2010acetyl aspartate\u2010to\u2010creatine (NAA\/Cr) and choline\u2010to\u2010creatine (Cho\/Cr) ratios were compared between coils using Wilcoxon signed\u2010rank tests. No significant differences were found between coil types. For long echo time, NAA\/Cr ratios were right thalamus 1.29\u00a0\u00b1\u00a00.27 versus 1.32\u00a0\u00b1\u00a00.34 (\n p<\/jats:italic>\n \u00a0=\u00a00.756) and left thalamus 1.22\u00a0\u00b1\u00a00.19 versus 1.22\u00a0\u00b1\u00a00.48 (\n p<\/jats:italic>\n \u00a0=\u00a00.301) for four\u2010channel versus eight\u2010channel coils, respectively. Cho\/Cr ratios were right thalamus 1.45\u00a0\u00b1\u00a00.28 versus 1.69\u00a0\u00b1\u00a00.68 (\n p<\/jats:italic>\n \u00a0=\u00a00.056) and left thalamus 1.51\u00a0\u00b1\u00a00.41 versus 1.45\u00a0\u00b1\u00a00.41 (\n p<\/jats:italic>\n \u00a0=\u00a00.215).
