Figure 1. . Selected examples of radiopaque embolization microparticle prototypes.

Figure 1. 

(A) Poly(2-hydroxyethyl methacrylate) microparticles incorporating barium sulfate – note the rough surface (inset: porosity can be seen on the magnified surface). (B) Microparticles of 3-(Methacryloylamido-acetamido)-2,4,6-triiodobenzoic acid-Hydroxyethyl methacrylate-EDMA copolymer (inset: porosity can be seen on the magnified surface). (C) Polyurethane microspheres containing entrapped Ta particulates (see magnified inset for tantalum particle size and shape). (D) Silicone microspheres with entrapped tantalum particulates. (E) Microspheres made from Hydroxyethyl methacrylate-2-[4-Iodobenzoyl]-oxo-ethylmethacrylate copolymers. (F) Poly(vinyl alcohol-co-2-acrylamido-2-methylpropane sulfonate) microspheres containing Lipiodol® (note the marbled appearance of the oil and water phases within the microspheres).
