(VSOP = very small superparamagnetic iron oxide particles) This new class of contrast agents with smaller particle size than SPIO offers advantages for MR angiography. SPIO particles are usually coated with an organic polymer such as dextran, carboxydextran or polyethylene glycol, which limits the minimal overall particle size that can be obtained.
VSOP-C184 consists of an aqueous solution of superparamagnetic iron oxide particles with a citrate coating and the overall particle size of 4-8 nm.
Short name: VSOP-C184, central moiety: Fe, concentration: 29 g Fe/l, relaxivity: R1=20.1, R2=37.1, B0=0.94 T. | |
