Explainable multiple abnormality classification of chest CT volumes

作者:

Highlights:

• We introduce a new task: explainable multilabel classification of chest CT volumes.

• We propose AxialNet, a CNN that identifies top slices per abnormality prediction.

• We prove that HiResCAM is guaranteed to highlight locations AxialNet used.

• A mask loss encourages AxialNet to predict abnormalities from within relevant organs.

• Our approach achieves state-of-the-art performance on the RAD-ChestCT dataset.
