This study shows that the expression of 3.0T1H-MRS in nasal polyps is significantly different from that in normal brain tissue, and there is a significant difference between the two (see Table 1, spectrum analysis Figure 1-2). The expression of Ace in nasal polyps was the highest (11.43 ± 6.11), NAA decreased significantly (17.76 ± 6.20), Cho increased (23.19 ± 6.91), Lac increased (12.51 ± 3.42), Lac / Ace ratio decreased most significantly (1.09 ± 0.56); Cho / NAA ratio increased significantly (1.34 ± 1.10); Lac / NAA ratio increased most significantly (0.70 ± 0.55); compared with the data of normal brain tissue in the same side, t-test had statistical significance.
