Radiographic studies have a major role to play in patients undergoing lung transplantation. A review of the findings associated with the reimplantation response, acute rejection, bronchiolitis obliterans, ischemia-induced air-way complications, and cyclosporine-associated lymphoma, as well as the pulmonary and cardiac change following double lung transplantation, has been presented. It should also be kept in mind that this group of patients is also subject to all of the usual problems associated with thoracic surgery, such as infection, atelectasis, pleural effusion, and pneumothorax, conditions for which radiologic assessment is crucial.
