Maria, In qdec there is not a built-in mechanism to restrict analysis to a particular region. By design it runs a whole-cortex analysis, masking just the medial (non-cortical) region, and then i suppose if your lucky (if your ROI is significant compared to everything else) your region will appear as a cluster which hopefully would survive a subsequent multiple-comparisons analysis. There might be a way to mask the glm analysis using the command line tools, but I dont think its recommended. Others might comment differently.
