[Selective intra-arterial perfusion of the cancerous breast: quantitative study]

Mammary tissue diffusion of a radioactive marker (Pertechnetate-Tc99m), intravenously or selectively and intraarterially injected, has been studied in 15 breast cancers; a considerable increase of that diffusion with co-injected degradable starch microspheres has been demonstrated. A clinical application of these techniques should be soon considered.
