Correlation between Ultrasound Grading of Diffuse Fatty Liver Changes with Density of Liver Measured by Computed Tomography Scan

Abstract

Ultrasound is a good imaging modality for diagnosing and grading fatty liver disease. It is an effective method for quantifying fatty liver alterations since it can be used to estimate mean liver density. Hepatic steatosis is another term for fatty liver. It occurs when the liver becomes clogged with fat. Small levels of fat in the liver are acceptable, but too much might cause health issues. Because considerable alcohol intake causes liver damage, fatty liver is classified as both non-alcoholic fatty liver disease and alcoholic fatty liver disease. The study aims to evaluate the correlation between US grading of fatty liver and computed tomography scan density of the liver, and assessment of the clinical significance of fatty liver changes detected by ultrasound in correlation with patient factors including age, gender, diabetes mellitus, smoking status, alcohol intake, and lipid profile. The collected dataset includes 110 patients that were evaluated by radiologists and diagnosed using Ultrasound and Computed Tomography scan departments at Al-Shaheed General Hospital Baghdad Resafa Health Directorate–Iraq. The experimental results show that the proportion of mates outperformed females by 58.2% and 41.8% respectively. Furthermore, it was noted that 32.7% of patients were diabetics, 66.4% of patients were fat, 25.5% of patients were current smokers, and 6.4% of patients were drinking. Moreover, 40.9% of patients had high s. cholesterol, 57.3% of patients had high s. TG, 14.5% of patients had high LDL, and 41.8% of patients had low HDL. Finally, it was concluded that the mean of liver density of US grades 2 or 3 (27.95) was less than 0 or 1 (35.51). Where, the prevalence of US grades 2 or 3 of fatty liver’s patients increased with increasing of BMI, until reaching 47.9% in obese patients.
