Describes cross sectional anatomy of the mediastinum , and lobar and segmental anatomy of the lung with teaching points and radiological guidelines and multiple examples of lobar and segmental pathologies and how we localize these pathologies .Also the types of chest CT images and indications of chest CT.

(0.625 to 2 mm slice thickness) often with a
high-spatial-frequency reconstruction
algorithm to detect and characterize
disease affecting the pulmonary
parenchyma and airways.
