Folic Acid-Conjugated Albumin-Stabilized Gold-Terbium Nanoparticles for SPCCT/MRI Imaging: An in vitro Cellular and Phantom Study

Introduction

Triple-negative breast cancer (TNBC) remains challenging to image because of its biological heterogeneity and the limitations of single-modality imaging. Multifunctional nanoparticles may provide complementary contrast for spectral photon-counting CT (SPCCT) and MRI, potentially improving multimodal tumor imaging.
