摘要
Introduction: In the modern world, owing to rapid urbanisation and changes in lifestyles and dietary habits, obesity has emerged as a leading problem. As a result, various morbid conditions have come into the picture which have severe effects on an individual's life expectancy. Visceral fat plays an important role in causing fatty liver. Aim: To determine the relationship between visceral fat area and liver fat using Computed Tomography (CT). Materials and Methods: A retrospective analytical study was conducted at Dr. D.Y. Patil Medical College, Hospital, and Research Centre Pune, Maharashtra, India. The CT scans of 134 patients who underwent CT scans of the abdomen pelvis and CT KUB/CT IVU between January 2022 and June 2022 were assessed by two experienced body imaging medical doctors. Subjects aged between 18 and 75 years were included without any co -morbidities like diabetes or hypertension. Waist circumference, subcutaneous fat area, and visceral fat area were calculated at the umbilical level. The CT attenuation value was measured in the right hepatic lobe, devoid of focal lesions and vessels, using a standard ROI of approximately 200 mm 2 . Similarly, as an internal control, splenic attenuation was also recorded. Statistical tests were employed to determine the significance of the obtained values, including Spearman's coefficient and Cohen's criteria. Results: The CT attenuation of the liver (fatty liver) showed a moderate correlation with visceral fat (Spearman's coefficient: 0.329). The association was statistically significant (p-value=0.0001). The CT attenuation of the liver (fatty liver) showed a weak correlation with subcutaneous fat (Spearman's coefficient: -0.269). The association was statistically significant (p-value=0.0016). The CT attenuation of the liver (fatty liver) demonstrated a weak -moderate correlation with waist circumference (Spearman's coefficient: -0.305). The association was statistically significant (p-value=0.0003). Conclusion: Visceral fat area has a stronger correlation with fatty liver than waist circumference and subcutaneous fat. Visceral fat should be considered a risk factor in the development of fatty liver, which may further lead to metabolic syndrome, in order to reduce mortality and morbidity related to it.
