Snapshots of 4D-T1w and 4D-T2w MRI at the exhalation and inhalation respiratory phases for patient 3, who was diagnosed with T4N2 adenocarcinoma. The tumour is radically treatable, but is embedded around the heart and oesophagus. Unlike T1w MRI, T2w MRI displays a high tumour-tissue contrast enabling tumour position and structure to be clearly delineated. Sliding motion of the tumour site against the chest wall is displayed in the sagittal plane and is more clearly presented in T2w than T1w MRI. Red arrows point to the tumour site and dashed white lines aid assessment of both superior-inferior diaphragm and sliding motion.
