Application Study on Isotope Tracing RRL Tumor Angiogenesis Imaging

Angiogenesis plays crucial roles in the progress of tumor growth,progression and metastases.The new tumor blood vessel tracer RRL can be targeted to the VEGFR-2 receptor on tumor vascular endothelial cells,Tracing with radioisotopes different types of tumor and angiogenesis in malignant tumor tissues with different invasive ability will provide the important information on the diagnosis,treatment and evaluated prognosis of malignant tumor.In this review,the recent study and progresses on molecular imaging with the peptide RRL in tumor angiogenesis will be summarized.
