Abstract: Objective To evaluate the diagnostic accuracy of quantitative ultrasound attenuation imaging parameters combined with the Residual Cholesterol/High-Density Lipoprotein Cholesterol (RC/HDL-C) ratio, in detecting hepatic steotosis in patients with metabolic dysfunction-associated fatty liver disease (MAFLD). Additionally, to investigate the correlation between these parameters and lipid metabolism in the context of liver fat infiltration. Methods A retrospective analysis was performed on the medical records of 146 patients with MAFLD who were examined at the People's Hospital of Handan City from January 2021 to December 2023 in . Based on the degree of hepatic steatosis, patients were categorized into mild, moderate, and severe groups. Differences in attenuation coefficient (AC), and RC/HDL-C levels among these groups were compared. The correlation between AC and RC/HDL-C was analyzed, and factors influencing liver fat infiltration in MAFLD were evaluated. Additionally, the diagnostic efficacy of AC and RC/HDL-C in assessing the severity of hepatic steatosis in MAFLD was examined. Results Among the 146 patients with MAFLD, 36 cases (24.66%) had mild hepatic steatosis, 58 cases (39.73%) had moderate steatosis, and 52 cases (35.62%) had severe steatosis. The AC for the mild, moderate, and severe groups were (0.71±0.22) dB cm-1 MHz-1, (0.80±0.25) dB cm-1 MHz-1, and (0.93±0.28) dB cm-1 MHz-1, respectively. The RC/HDL-C ratios were (0.18±0.04), (0.22±0.05), and (0.23±0.07), respectively. The differences were statistically significant (P<0.05). Both AC (OR=3.677, 95% CI: 1.085-12.453) and RC/HDL-C (OR=4.133, 95% CI: 1.221-13.998) were identidied as risk factors for the severity of hepatic steatosis in MAFLD patients (P<0.05). The sensitivity and specificity for diagnosing moderate to severe liver steatosis using AC, RC/HDL-C, and their combination were 0.61, 0.68, and 0.77, respectively, with corresponding area under the curve(AUC) values of 0.736, 0.738, and 0.829. Conclusion AC, RC/HDL-C can serve as auxiliary diagnostic tools for assessing the degree of hepatic steatosis in MAFLD, demonstrating good diagnostic efficacy.
