Developing a lung nodule management protocol specifically for cardiac CT: Methodology in the DISCHARGE trial.

•No lung nodule management algorithm exists specifically for cardiac CT.•The DISCHARGE trial is a pragmatic prospective randomized trial currently being undertaken across 16 countries in Europe for patients with stable chest pain.•As part of the trial a lung nodule algorithm is being evaluated based on modified lung-RADS nodule management algorithms.•The methodology of this ‘Lung-RADS for cardiac CT’ algorithm is presented.
