  \caption{Comparison with state-of-the-art, for the task NC vs AD. Accuracy of our models (in green) contrasted with the models reviewed (in gray) and with the average value of the state-of-the-art models (in blue). 'PET' denotes  models trained with PET scans only; 'MRI' denotes models trained with MRI scans only; 'without AM' denotes  models without attention mechanism; 'with AM' denotes models that use attention mechanism; 'Supervised AM' refers to our models with supervised attention mechanism (there are no other state-of-the-art models in this category). Finally, on the right, the model with ROI, which was the best performing model.}
