Abstract
BACKGROUND

Liver imaging and transient elastography (TE) are both tools used to assess liver fibrosis and steatosis among people with hepatitis C virus (HCV) infection. However, the diagnostic accuracy of conventional imaging in detecting fibrosis and steatosis in this patient population remains unclear.

AIM

To investigate the correlation between steatosis and fibrosis and abnormal findings on liver imaging in patients with HCV.

METHODS

We conducted a retrospective cross-sectional analysis of patients with HCV at Grady Liver Clinic who had TE exams between 2018-2019. We analyzed the correlation of controlled attenuation parameter and liver stiffness measurement on TE and abnormal findings on liver imaging. Liver imaging findings (hepatic steatosis, increased echogenicity, cirrhosis, and chronic liver disease) were further evaluated for their diagnostic performance in detecting fibrosis (≥ F2, ≥ F3, ≥ F4) and steatosis (≥ S1, ≥ S2, ≥ S3).

RESULTS

Of 959 HCV patients who underwent TE, 651 had liver imaging. Higher controlled attenuation parameter scores were observed in patients with abnormal liver findings (P = 0.0050), hepatic steatosis (P < 0.0001), and increased echogenicity (P < 0.0001). Higher liver stiffness measurement values were also noted in those with abnormal liver (P < 0.0001) and increased echogenicity (P = 0.0026). Steatosis severity correlated with hepatic steatosis (r = 0.195, P < 0.001) and increased echogenicity (r = 0.209, P < 0.001). For fibrosis detection, abnormal liver imaging had moderate sensitivity (81.7%) and specificity (70.4%) for cirrhosis (≥ F4), while cirrhosis on imaging had high specificity (99.2%) but low sensitivity (18.3%). Increased echogenicity showed high specificity (92.8%) but low sensitivity (20.9%) for steatosis detection.

CONCLUSION

Liver imaging detects advanced fibrosis and steatosis but lacks early-stage sensitivity. Integrating TE with imaging may improve evaluation in patients with HCV.

Core Tip: Conventional liver imaging and transient elastography (TE) are commonly used to assess liver fibrosis and steatosis in individuals with hepatitis C virus. This study evaluates the diagnostic performance of imaging findings in detecting fibrosis and steatosis across different disease stages and their correlation with TE measurements. While imaging demonstrates high specificity for advanced liver disease, its limited sensitivity in earlier disease stages underscores the need for a multimodal approach. These findings help inform clinicians in resource-limited settings on the strengths and limitations of liver imaging when TE is unavailable.
