Literature Review 

Analysis of In Vivo Hepatic Steatosis 

Cui, Hu, Han, Yang, and Li (2017) utilized the Small Animal MRI System to analyze the body composition of mice to study hepatic steatosis. Eight-week-old male C57BL/6 mice were fed a high-fat and high-sucrose diet for four to sixteen weeks. This was done to induce obesity in the mice, which is one of the key risk factors of nonalcoholic fatty liver disease (NAFLD) of which Hepatic steatosis is the earliest stage of NAFLD. The Small Animal MRI System measured the body fat mass, lean mass, and fluids of the mice. The whole body of the mice and their livers were scanned using a 0.55 T magnet with the device. The results indicated that the subjects’ body weight increased to 45±1.2 g after 16 weeks of feeding on the high-fat, high-sucrose diet. Overall results from the MRI analysis indicated that hepatic steatosis and obesity increased with the high-fat and high-sucrose diet.

Strengths 

The Small Animal MRI System has a permanent tesla magnet that provides high magnetic field uniformity and minimal eddy current effect. The system allows high-quality anatomy imaging with a high resolution of < 0.08 mm. The MRI software is user-friendly. It includes multiple sequences for full MRI capabilities. The system is non-destructive, with no risk or negligible running costs since it doesn’t require cryogenic gases. Two models of the system are available to suit your experimental needs. The system can be used for several applications in several life science fields, including oncogenic research, pharmacological research, and studying obesity and cardiovascular disease models.
