Summary

The goal of this observational study is to evaluate changes in adipose tissue and skeletal muscle distribution using magnetic resonance imaging (MRI) in adults with obesity undergoing bariatric surgery. The study also aims to investigate the relationship between MRI-derived body composition parameters and metabolic outcomes following surgical treatment of obesity. The main questions it aims to answer are:

How does bariatric surgery affect the distribution of visceral, subcutaneous, hepatic, perirenal adipose tissue and skeletal muscle over 12 months? Are changes in MRI-derived body composition associated with improvements in metabolic parameters after bariatric surgery?

Participants will:

undergo MRI examinations before bariatric surgery and at 1, 6, and 12 months after surgery; undergo routine clinical and metabolic assessments during standard postoperative follow-up; have MRI-derived body composition measurements correlated with metabolic outcomes over the 12-month follow-up period.

Conditions

  • Obesity (BMI>30)

Interventions

DIAGNOSTIC_TEST

MRI

Magnetic resonance imaging (MRI) will be used to assess body composition before bariatric surgery and at 1, 3, and 12 months after surgery. MRI examinations will quantify visceral and subcutaneous adipose tissue, skeletal muscle volume, intramuscular fat, hepatic fat, and perirenal fat. Imaging findings will be analyzed longitudinally and correlated with routine clinical and metabolic parameters to evaluate changes in body composition following bariatric surgery.
