Learning to detect chest radiographs containing pulmonary lesions using visual attention networks

Lung cancer is the most common cancer worldwide and the second most common cancer in Europe and the USA (Ferlay et  al., 2013; American Cancer Society, 1999). Due to delays in diagnosis, it is typically discovered at an advanced stage with a very low survival rate (Cancer Research UK, 2014). The chest radiograph is the most commonly performed radiological investigation in the initial assessment of suspected lun g cancer because it is inexpensive and delivers a low radiation dose. On a chest radiograph, a nodule is defined as a rounded opacity  ≤  3cm, which can be well- or poorly marginated.
