INJECTABLE CARBON COMPOSITIONS IN STABLE AQUEOUS SUSPENSION; METHOD FOR PREPARING THEM AND METHOD OF PRESURGICAL MARKING IN THE INVESTIGATION OF NONPALPABLE MAMMARY PATHOLOGIES BY APPLYING SAID COMPOSITIONS

摘要

Injectable activated carbon suspensions are proposed for the presurgical marking of nonpalpable mammary pathologies for the purpose of achieving better diagnosis and treatment.These are suspensions that flow freely and without the formation of obstructing aggregates in the needles used during their application, with carbon particles of micron granulometry limited to less than 50mu and preferably between 2mu and 6mu in concentration of approximately 4.0% p/v in saline aqueous medium. A process is also proposed for preparing said compositions.
