Nanoparticle-based local drug treatment has potential for chemotherapy for cervical tumors, but there is a need for real time in vivo imaging of the particle delivery to monitor therapeutic efficacy. We are interested in using Chemical Exchange Saturation Transfer (CEST), a molecular MRI contrast mechanism, to monitor the vaginal delivery of drug-loaded nanoparticles to treat local cervical tumors by co-encapsulating CEST contrast agents and drugs within liposomes. The goal is to image the distribution of these particles and to indirectly assess the retention of drugs over the course of treatment.
