1) Understand that nodules < 10 mm are seen in many conditions and that the differential diagnosis on HRCT is based on the size of the nodules, their appearance, and their distribution. 2) Understand that ground glass opacity is a non-specific pattern that reflects the presence of abnormalities below the resolution of HRCT. 3) Understand that the differential diagnosis of ground glass opacity is based on the clinical history (in particular the duration of symptoms), the distribution of the ground glass opacity, and the presence of associated abnormalities.
