Maximum activation maps for layers 2, 10, 17 and 24 of the Linear model for input images representing different grades of cardiac uptake. Activation maps demonstrate that the convolutional neural network model finds abnormal myocardial signal in patients with cardiac uptake suggestive for ATTR and not extracardiac features, similarly to standard clinical reading by a physician
