Figure 2 ¹H magnetic resonance spectroscopy spectrum characteristics for different fatty liver pathological levels. MRS shows short a low fat peak in the no fatty liver group (A1, A2); In mild fatty liver pathological images (B1), lipid droplets increased slightly [hematoxylin-eosin (HE), magnification × 200]; ¹H magnetic resonance spectroscopy (¹H MRS) for mild fatty liver showed a slightly increased fat peak (B2); In moderate fatty liver pathological images (C1), lipid drops relatively increased compared with mild fatty liver (HE, magnification × 200); ¹H MRS for moderate fatty liver showed a significantly higher fat peak (C2); In severe fatty liver pathological images (D1), the full field distribution of large bubble lipid droplets (HE, magnification × 200); ¹H-MRS for severe fatty liver showed a significantly higher fat peak close to the water peak (D2).
