Abstract
The assessment of vascular permeability of malignant tumor plays an important role in the diagnosis and treatment of cancer. Dynamic contrast-enhanced magnetic resonance image (DCE-MRI) using Gd-encapsulated carbonaceous dots and Gd-DTPA-BMA as contrast agents was performed in 4T1 mouse breast cancer and HCC827 human non-small-cell lung cancer (NSNLC) xenograft models. Histopathological parameters of tumor vascularity microvessel density (MVD), microvessel area (MVA), endothelial area (EA) and α-SMA CD31 Co-expression (α-SMA/CD31%) were compared with the DCE-MRI parameters. Results demonstrated that DCE-MRI with the new nanoparticle Gd@C-dots can noninvasively evaluate vascular permeability. Ktrans measured by DCE-MRI with Gd@C-dots is an accurate parameter for the characterization of tumor permeability. EA is a reliable microvessel parameter to evaluate vessel permeability.
