Chest CT Patterns of Interstitial Lung Disease 

In this presentation, Dr. Elsie Nguyen, an associate professor of radiology at the University of Toronto, discusses the patterns of interstitial lung disease observed in chest CT scans. She outlines a systematic approach for identifying these patterns, covering aspects such as increased and decreased lung attenuation, air trapping, cystic lung disease, reticulation, and nodules. Dr. Nguyen emphasizes the importance of comparing current findings with prior images, considering patient history, and utilizing electronic patient records. Throughout the presentation, she provides examples and case studies, including a focus on COVID-19 pneumonia, bronchiolitis obliterans syndrome, and cystic lung diseases like pulmonary Langerhans cell histiocytosis and lymphangiomatosis. The presentation aims to empower healthcare professionals with the knowledge and confidence to interpret chest CT scans for interstitial lung disease.
