This review explores using multivalent polymerized vesicles (PVs) with MRI and gamma scintigraphy for in vivo imaging of vascular molecular receptors. This approach enables targeted therapies and personalized medicine for conditions like cancer and multiple sclerosis (MS).

Area of Science:

  • Biomedical imaging
  • Nanotechnology
  • Molecular imaging

Background:

  • Vascular molecular receptors are key targets for diagnosing and treating diseases.
  • Current imaging techniques have limitations in specificity and targeting.
  • Polymerized vesicles (PVs) offer a versatile platform for developing novel imaging agents.

Purpose of the Study:

  • To review the application of multivalent polymerized vesicles (PVs) combined with MRI and gamma scintigraphy for in vivo imaging of vascular molecular receptors.
  • To present data on designing and validating targeted imaging agents in preclinical models.
  • To discuss the potential of this technology for personalized vascular-targeted therapies.

Main Methods:

  • Development of multivalent polymerized vesicles (PVs) as imaging agents.
