Microspheres and Nonspherical Particles for Embolization

Last years, calibrated microspheres have proven their superiority in targeting embolization over non spherical particles in many applications. For the very near future they represent the best tool for controlling drug delivery in chemoembolization, under the two conditions that they would be image detectable and that the dosimetry would be tailored to pathological process.
