Examples of the CNN prediction visualisations are shown in yellow for two true positive cases. Segmental and subsegmental arteries of the upper lobes are reduced in diameter and are smaller than the accompanying bronchi (arrows in (a)). Abrupt narrowing of the left superior lingular artery (arrow in (b)) and reduction of pulmonary artery diameter (arrowheads in (b)) are seen as signs of chronic pulmonary embolism
