Unlabelled: Patients with hepatitis C virus (HCV) infection present higher risk of developing type-2 diabetes mellitus (DM). However, the mechanism of this association and the role of antiviral treatment are still unclear. The objective of this study was to investigate the relationship between the use of peguilated interferon and the development of insulin resistance (IR) in these patients.

Materials And Methods: Twenty-five patients known to have or suspected of having hepatic lesions who were eligible for surgery underwent dual-phase (ie, arterial and portal phase) helical CT and phased-array MR imaging (ie, unenhanced fast spin-echo T2-weighted imaging and gradient-echo T1-weighted imaging performed before and after administration of mangafodipir trisodium). All images were reviewed independently by three off-site blinded reviewers who separately reviewed the CT scans and MR images.
