This document provides an overview of chest CT, including its advantages over standard x-rays, different types of CT scans, and a systematic approach to interpreting chest CT scans. It discusses interpreting various lung abnormalities visible on CT such as pneumonia, COPD, atelectasis, interstitial lung disease, pulmonary embolism, and nodules. Different windows and views used in chest CT are also outlined.
