Multiparametric MRI for Characterization of Hepatocellular Carcinoma

This prospective, monocentric, observational study evaluates the clinical utility of multiparametric magnetic resonance imaging (mpMRI) in the characterization and management of hepatocellular carcinoma (HCC). The study focuses on how advanced MRI techniques-such as diffusion-weighted imaging (DWI), dynamic contrast-enhanced MRI (DCE-MRI), and quantitative mapping (T1/T2)-can provide functional insights into tumor biology.

Conducted at a German university hospital, the study investigates whether mpMRI can improve diagnostic precision and assist in therapeutic decision-making for patients undergoing locoregional treatments like transarterial chemoembolization (TACE) or selective internal radiotherapy (SIRT).

By integrating multiple MRI biomarkers, the study aims to explore correlations between imaging features and treatment response. Imaging protocols follow current clinical standards, and the study introduces no investigational agents. Radiological evaluations are performed by expert radiologists, and statistical analysis is pre-specified. The study complies with ethical and data protection standards.
