Abstract
The invention provides the use of a physiologically tolerable, particulate, free or matrix-borne, ferrimagnetic or ferromagnetic material for the manufacture of a diagnostic agent for administration into the gastrointestinal tract, the reproductive tract, the urinary tract, a closed body cavity (e.g. into the synovial fluid or the vasculature) or the musculature for magnetometric imaging of the human or non-human animal body.
Claims4
A method of generating a magnetometric image of the human or non-human animal body which method comprises administering into the gastrointestinal tract, the reproductive tract, the urinary tract, a closed body cavity or the musculature of said body a physiologically tolerable particulate-ferromagnetic or ferrimagnetic material and generating a magnetometric image of at least a part of said body into which said material distributes.
A process for detecting variations in magnetic susceptibility within a human or non-human animal body which process comprises administering into the gastrointestinal tract, the reproductive tract, the urinary tract, a closed body cavity or the musculature of said body a physiologically tolerable particulate ferromagnetic or ferrimagnetic material, and with a magnetometer continuously or repeatedly monitoring the magnetic susceptibility of at least a part of said body into which said material distributes whereby to generate magnetometric images of variations or abnormalities in blood flow, or to monitor the location and aggregation of these materials within regions of the body, and generate a magnetometric image thereof.
