Core Tip

Core Tip: Use of single biomarkers might hinder the detection efficiency of existing hepatocellular carcinoma (HCC) molecular probes due to tumor heterogeneity, while negative (T2) contrast agents could result in inaccurate diagnoses. Therefore, we developed double-antigen-targeting magnetic resonance imaging (MRI) probes for hepatic tumors by conjugating alpha-fetoprotein or glypican-3 antibodies simultaneously to a 5-nm ultra-small superparamagnetic iron oxide (USPIO) and investigated its performance in orthotopic HCC mouse model. The bi-specific T1-positive contrast-enhanced MRI probe for HCC demonstrated increased specificity and sensitivity to diagnose early-stage HCC irrespective of tumor size and/or heterogeneity. Moreover, the in vivo enhancement of imaging by the USPIO probes appeared dose-dependent and requires further investigation.
