1. To show the classification of bronchiolitis with radio-pathological correlation 2. To provide an easy and schematic diagnostic approach, based on HRCT findings and relevant clinical information 3. To emphasize the role of post-processing techniques: MIP, MinIP and densitometric evaluation  

1. Introduction 2. Anatomy and histology of the pulmonary secondary lobule 3. HRCT imaging: contribution of MIP and MinIP reconstructions    a. Direct signs: Centrilobular Nodules and Tree-in-Bud patterns    b. Indirect signs: Mosaic attenuation and Air trapping patterns 4. Dual-Energy CT imaging and post-processing techniques in air trapping quantification. 5. Classification of Bronchiolitis: HRCT findings with pathologic correlation    a. Cellular bronchiolitis       i. Infections       ii. Hypersensitivity pneumonitis       iii. Aspiration       iv. Respiratory bronchiolitis       v. Follicular bronchiolitis       vi. Diffuse panbronchiolitis    b. Constrictive bronchiolitis       i. Swyer-James syndrome       ii. Post-transplantation       iii. Systemic lupus erythematosus       iv. Inhalational disease       v.
