The aim of this work is to give a generalization of Gabriel's Theorem on coherent sheaves to coherent twisted sheaves on noetherian schemes. We start by showing that we can recover a noetherian scheme X from the category Coh(X, alpha) of coherent alpha-twisted sheaves over X, where alpha lies in the cohomological Brauer group of X. This follows from the bijective correspondence between closed subsets of X and Serre subcategories of finite type of Coh(X, alpha). Moreover, any equivalence between Coh(X, alpha) and Coh(Y, beta), where X and Y are noetherian schemes, and alpha is an element of Br' (X), beta Br' (Y) induces an isomorphism between X and Y.
