IMPROVEMENTS IN OR RELATING TO DIAGNOSTIC IMAGING

摘要

The invention relates to the administration of dynamic, particulate dispersion systems, e.g. gas-containing diagnostic contrast agents, more particularly to apparatus and a method for the controlled and substantially steady state administration of such gravity segregating dispersions by infusion. Controlled delivery of substantially homogeneous gravity segregating dispersion, e.g. gas-containing contrast agent, may be achieved by an infusion procedure in which the dispersion is delivered from a syringe or other preferably cylinder shaped reservoir, e.g. tubing, which is exposed to a thermal gradient across its body.
