A preclinical study of a novel dual-modality contrast agent in rodent models.

ABSTRACT:

Introduction

Glioblastoma (GBM) represents the most aggressive and prevalent form of primary malignant brain tumor in adults, with surgical intervention being the primary treatment modality. To enhance surgical outcomes and extend patient survival, we have engineered a dual-modality MRI/FI contrast agent known as PL002 to aid in the surgical management of GBM.

Methods

In this study, an orthotopic glioma model was established in mice via intracranial injection of U-87 MG cells. Subsequently, the model animals were intravenously injected with PL002 and placed in a 7.0T magnetic resonance imaging (MRI) device to evaluate the imaging effects. After the MRI scan, fluorescence imaging techniques were employed to observe the distribution of PL002 at both the brain tissue and cellul
