FeraSpin XS is an ultra-small super-paramagnetic iron oxide nanoparticle agent for MR angiography (MRA). It has been size-selected from FeraSpin R and is part of the FeraSpin Series. FeraSpin XS has the longest circulation time of the entire FeraSpin product family and can be imaged by both T1- (positive contrast) and T2/T2*- weighted sequences.

Viscover’s unique ultrasmall superparamagnetic iron oxide nanoparticle (USPIO) agent:

  • Is analogous to human clinical agents
  • Has an ultra-small size of 18 nanometers
  • Has the longest blood half-life of all FeraSpin products
  • Delivers optimal vascular T1 positive enhancement
  • FeraSpin XS is Viscover’s leading agent for nanoparticle-based vascular studies

Apply FeraSpin XS to effectively:

  • Visualize and quantify vascularization of tumors and inflammatory processes
  • Determine the vascular volume fraction and conduct vessel size imaging
