CONT

OEM [otite externe maligne] et scintigraphie au gallium (Ga67). Le citrate de gallium est un traceur bien connu de l'inflammation et de l'infection grâce à sa liaison directe aux leucocytes et à sa complexation avec la lactoferrine issue de l'inflammation : il se fixe sur tout foyer infectieux actif, que celui-ci soit limité aux parties molles (comme dans l'OES [otite externe sévère]) ou étendu à l'os (dans l'OEM) : une fixation du Ga67 n'est donc pas spécifique d'une OEM.

CONT

[...] la fixation du FDG [fluorodésoxyglucose] est liée à une augmentation locale de l'entrée cellulaire du glucose, la fixation du gallium-67 repose sur de multiples mécanismes complexes (liaison à la transferrine, fixation lysosomiale).
