Estratto
I mezzi di contrasto per ecografia, come già ampiamente argomentato, sono costituiti da microbolle delle dimensioni di 3–5 µm che, iniettate in bolo, aumentano il segnale ultrasonografico proveniente dal letto vascolare o capillare, e forniscono un’adeguata rappresentazione del flusso ematico del microcircolo di un tessuto o di un organo (ecoangiografia perfusionale). Poiché questi composti non si distribuiscono nei liquidi tissutali ma rimangono nei vasi, la loro cinetica è differente da quella degli altri mezzi di contrasto utilizzati in radiologia per la TC o la RM.
