Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

On the basis of previous research, this subject intends to evaluate the liver improvement of patients with liver disease after weight loss by MRI, and quantify it by extracting features, so as to provide a new method to judge the liver status of patients with liver disease, and to evaluate the correlation between the inflammatory status of patients and the quantitative features of MRI, and try to explain the reasons for the improvement of fatty liver status of patients with liver disease after weight loss. To provide a new theoretical basis for fatty liver and systemic inflammatory liver damage in patients with liver disease after weight loss surgery, and to link them, and try to explain the improvement of fatty liver in patients with liver disease through the reduction of systemic inflammatory level.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is a prospective study to explore the improvement of fatty liver and severe state of the whole body in patients with liver disease undergoing weight-loss surgery. The research object is obese patients who underwent laparoscopic sleeve gastrectomy in our hospital. According to the standard of accepting the discharge, about 50 patients were selected and divided into groups according to preoperative, postoperative one month, postoperative three months and postoperative six months.All patients underwent routine sequence examinations using a Siemens 3.0T MRI scanner (MAGNETOM Prisma, Siemens Healthcare, Munich, Germany).This study investigates alterations in NAFLD among patients with obesity who underwent bariatric surgery using MRI-PDFF and MRS techniques. Additionally, we evaluated the factors that may influence these changes in patients after the surgical procedure.
