Hepatosellüler Karsinomun Ortotopik Fare Modelinde Non-İnvaziv PET/MR Görüntüleme

Overview

This study presents a protocol for creating orthotopic hepatocellular carcinoma (HCC) xenografts, with a focus on non-invasive imaging of tumor hypoxia. The method utilizes positron emission tomography (PET) imaging with [18F]Fluoromisonidazole and [18F]Fluorodeoxyglucose to monitor tumor hypoxia in vivo.
