There is also a dextran–peptide conjugate23 targeting EDB-FN, consisting of an antimagnetic and biocompatible dextran and a targeting peptide, and the dextran can be directly detected by CEST.CM-101 and MT218 are contrast compounds that target specific tumor stromal components and can provide comprehensive imaging of tumor tissues and metastases as well as monitor biological changes following treatment. This evidence concerns the gene FN1 and neoplasm.
