Grad-CAM heatmaps for False Positive COVID-19 predictions. The red intensity of the images on the right indicates the important regions for a false positive prediction. These regions correspond to multiple consolidations with no zone predominance in the right lung (a), a unilateral right lower lung opacity and the contralateral soft tissues in the axillary region (b), superimposition of the scapula in the right lung periphery along with the left lower lobe vessels behind the heart (c)
