This course provides a focused overview of thoracic imaging in lung cancer and oncology patients. It covers key principles of lung cancer screening, including criteria for positive findings and important incidental features to report. Participants will gain skills in evaluating cardiovascular findings on chest CT, recognising treatment-related complications, and identifying vascular emergencies such as pulmonary embolism. The course also addresses characterisation of mediastinal tumours using CT and MRI, and assessment of treatment response, including progression and pseudo-progression, to support accurate reporting and optimal patient management.
