Diagnostic Value of the Color Doppler Ultrasound Standardized Semiquantitative Score Combined With Sound Touch Elastography in Liver Fibrosis in Patients With Chronic Hepatitis B: A Retrospective Cohort Study

Abstract

Purpose This study aims to evaluate the diagnostic value of standardized semiquantitative scoring of color Doppler ultrasound combined with liver stiffness measurement (LSM) of sound touch elastography (STE) in chronic hepatitis B (CHB) patients, providing a reference for the liver fibrosis diagnosis. Methods We performed ultrasound and STE on CHB patients, with liver biopsies as the benchmark. We compared the differences in ultrasound standardized semiquantitative scoring and LSM among patients with different stages of liver fibrosis, and evaluated the diagnostic efficacy of significant liver fibrosis using receiver operating characteristic (ROC) curves and the area under the ROC curve alone or in combination. Results The total scores of ultrasound semiquantitative scoring and LSM showed statistically significant differences among patients with different stages of liver fibrosis (P < 0.05). There was no statistically significant difference in the total scores of S0 and S1 stages or in the LSM values (P > 0.05). However, the total scores and LSM values for patients at stages S2 and S3 were both higher than those at stage S0, and increased with the severity of fibrosis staging, with statistically significant differences (P < 0.05). The results of the ROC curve analysis showed that the combined diagnosis of significant liver fibrosis with ultrasound standardized semiquantitative scoring and STE had an area under the curve of 0.807, which was significantly greater than using ultrasound standardized semiquantitative scoring (0.694, P < 0.05) or shear wave elastography alone (0.706, P < 0.05). Conclusions Color Doppler ultrasound with standardized semiquantitative scoring combined with STE examination can detect significant liver fibrosis (≥S2) in CHB patients.
