Despite recent advances in surgical techniques, postoperative complications arise in 24-41% of patients undergoing thoracic surgery. Here we present an MRI protocol for the pre and postoperative assessment of chest wall and diaphragmatic motion which provides valuable dynamic information to aid radiological assessment in these highly variable patients. We also propose a novel method for fully automated extraction of the diaphragm motion which can provide an additional tool to aid radiologists in making the distinction between expected and adverse postoperative pathologies.
