    Dear Editor,
    We agree with Dr. Alberto Signore and his letter [1] nicely defines inflammation and infection, which we did not make clear enough in our review [2]. However, the endothelial molecules guiding the migration of leukocytes to sites of inflammation and infection are practically taken the same as infection always has inflammatory components. Therefore, it is highly unlikely that imaging endothelial molecules one can easily discriminate between infection and inflammation.
