Liver assessment using Gd-EOB-DTPA-enhanced magnetic resonance imaging in primary biliary cholangitis patients

Abstract

Purpose

To evaluate the feasibility of utilizing gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance imaging (MRI) for the assessment of Child–Pugh class and for differentiating between patients with primary biliary cholangitis (PBC) and posthepatitic cirrhosis.

Materials and methods

45 PBC patients and 45 posthepatitic cirrhosis patients were enrolled and Gd-EOB-DTPA-enhanced MRI was applied. The average relative signal enhancement (RE) of the liver and average contrast to noise ratio (CNR) of common bile duct at 4, 20, and 50 min between different Child–Pugh classes of PBC patients were compared. The RE and CNR in all timepoints in patients with the same Child–Pugh class were compared between PBC patients and posthepatitic cirrhosis patients.

Results

The RE of liver and CNR of common bile duct at 4, 20, and 50 min was significantly different between all Child–Pugh classes of PBC patients_. There were also no significant differences in the RE of liver and CNR of common bile duct in all timepoints between patients with PBC and posthepatitic cirrhosis in the same Child–Pugh class.

Conclusion

Gd-EOB-DTPA-enhanced MRI is feasible for liver function assessment in PBC patients. However, the ability of this modality in differentiating liver cirrhosis of different etiologies requires further investigation.
