Contras agent having an imaging agent coupled to viable granulocytes for use in magnetic resonance imaging of abscess and a method of preparing and using same

摘要

A method and contrast agent for magnetic resonance imaging (MRI) of abscess. Granulocytes are separated from whole blood and incubated with an imaging vehicle such as magnetite. The granulocytes encapsulate the imaging vehicle and are suspended in an intravascularly administrable carrier to form the contrast agent. The contrast agent is highly specific for MRI of abscess.
