An Introductory Primer of Pulmonary HRCT:
Anatomic Approach with Pathologic Correlation

Table of Contents

• Technical aspects of HRCT
• Lung anatomy I
• Lung anatomy II
• Basic HRCT patterns
  Linear abnormalities
  Nodules
  Consolidation
  Ground-glass opacity
  Cysts/Lucencies
• HRCT findings in diseases: The cases are presented as unknowns.
  Core group--Cases 1 through 7. Do these first and in order after completing Lung Anatomy I, II, and Basic HRCT Patterns.
  Supplementary group--Cases 8 through 29. Application of principles

  Note: An index is provided for accessing cases for review. It is intended for use as a reference after completing the cases as unknowns.

  Optional Links
  Review of routine chest CT anatomy
  Review of normal lung histology
