Abstract

Cette invention concerne d'une manière générale une carte-index comprenant des informations à la fois de pression et de perfusion relatives au pied d'un patient diabétique à des fins de traitement. La carte-index peut également être une carte de perfusion et/ou métabolisme des tissus (reflétant l'apport d'oxygène et l'extraction d'oxygène) obtenue par imagerie thermique, imagerie hyperspectrale ou par balayage par ultrasons duplex, angiographie par résonance magnétique (ARM), tomographie par ordinateur (CT) ou imagerie Doppler à laser. Ces informations contribuent au traitement en prévention de l'ulcération et de l'amputation du pied diabétique et au traitement de tissus touchés en prévention de la perte de tissus dans d'autre régions du corps.
