Preferred Label : Iodinated Polyethylene Glycol-based Hydrogel Tissue Marker;
NCIt synonyms : PEG-based Hydrogel Tissue Marker; Radiopaque Polymer Hydrogel Imaging Agent;
NCIt definition : A radiopaque hydrogel containing cross-linked, iodinated polyethylene glycol (PEG)
particles in a viscous carrier, with potential use as a contrast agent to enhance
marking of soft tissue during a surgical procedure and concomitant radiotherapy upon
computed tomography (CT), magnetic resonance (MR) and ultrasound imaging. Upon intratumoral
injection, iodinated PEG-based hydrogel tissue marker localizes to and is maintained
in soft tissue. Upon MR, ultrasound and/or CT imaging, the visualization of the tumor
tissue is enhanced, which can facilitate tumor removal and image-guided radiotherapeutic
treatment. The hydrogel particles are stable and visible through 3 months, after which
they liquefy, and are absorbed by the body and cleared in the urine.;
