Abstract:
Objective:To explore the diagnostic performance of ultrasound attenuation imaging (ATI) in grading the degree of hepatic steatosis in metabolic dysfunction-associated fatty liver disease (MAFLD).Methods:The liver gray-scale ultrasound and ATI examinations were performed on 212 subjects who were treated in Zhongshan Hospital Affiliated to Fudan University from August 2020 to March 2021. The attenuation coefficient(AC) values among different degrees of hepatic steatosis were analyzed and the diagnostic performance of ATI was evaluated. Relationships between AC values and clinical characteristics were assessed by Pearson′s correlation analysis.Results:The AC values for normal liver, mild, moderate and severe fatty liver were (0.56±0.05)dB·cm -1·MHz -1, (0.68±0.09)dB·cm -1·MHz -1, (0.82±0.09)dB·cm -1·MHz -1, (0.94±0.09)dB·cm -1·MHz -1, respectively. There were significant differences in AC values among different hepatic steatosis divisions( P<0.008). There was highly significant correlation between AC values and the degree of hepatic steatosis( r=0.860, P<0.01), moderate correlation between AC values and BMI( r=0.425, P<0.01), weak correlation between AC values and HDL-C( r=-0.237, P=0.029), no correlations between AC values and age, TC, TG, LDL-C ( r=0.083, 0.055, 0.133, -0.039, all P>0.05) .The areas under the receiver operating characteristics curve of ATI for mild fatty liver and above, moderate fatty liver and above, severe fatty liver and above were 0.958, 0.962, 0.918; the sensitivity were 90.1%, 95.8%, 94.9%, the specificity were 96.1%, 87.1%, 73.9%, and the cut-off values were 0.666 dB·cm -1·MHz -1, 0.719 dB·cm -1·MHz -1, 0.803 dB·cm -1·MHz -1, respectively. Conclusions:ATI is a reliable and convenient method for evaluating the degree of hepatic steatosis in MAFLD.
