 This study found that ultrasonography can accurately measure various types of abdominal fat deposits, including subcutaneous, omental, preperitoneal, retroperitoneal, and perirenal fat. It also demonstrated that women have thicker subcutaneous fat than men, while men have larger omental fat. Additionally, postmenopausal and diabetic patients had changes in their omental fat, while those with fatty liver disease had thicker preperitoneal and perirenal fat. Furthermore, the study found that a cutoff of 54 mm in males and 34 mm in females of omental fat and 22.5 mm in males and 12.5 mm in females of perirenal fat could be used to identify individuals who are at risk for metabolic syndrome.
