Built for the reader who must turn a gray-scale volume into a confidence-graded diagnosis before the multidisciplinary team convenes, this reference grounds every HRCT read in the anatomy of the secondary pulmonary lobule, then carries that foundation through a fixed distribution-pattern-ancillary-findings algorithm into a four-tier confidence framework that states, in one honest word, how far a single study can carry a diagnosis alone. It moves from the fibrotic differential that decides biopsy and antifibrotic eligibility, through the nodular, cystic, and airway-centered patterns that define sarcoidosis, LAM, and small airways disease, into the acute and special-population contexts where the same discipline must hold under real technical constraint. It serves the thoracic radiology fellow, the resident on chest call, and the pulmonologist reading alongside radiology.
Confidence-tiered pattern callouts, cross-referenced cases, and a consolidated point-of-care atlas turn a compressed differential into a defensible report.
Inside, You Will Learn How To
- Grade the UIP call - apply the typical, probable, indeterminate, and alternative-diagnosis tiers that decide whether idiopathic pulmonary fibrosis needs biopsy.
- Separate NSIP from UIP - read subpleural sparing and symmetry against the finding whose absence caps a pattern below typical.
- Read exposure into the image - apply multilobar air trapping and the head-cheese sign to redirect fibrosis toward hypersensitivity pneumonitis.
- Stage sarcoidosis and defend it - correlate perilymphatic nodularity and centrilobular sparing against carcinomatosis, silicosis, and infection.
- Name the cyst - distinguish LAM, Birt-Hogg-Dubé syndrome, and lymphocytic interstitial pneumonia by shape, distribution, and wall.
- Confirm the mosaic - apply expiratory accentuation to separate airway-obstructive from vascular causes, including chronic thromboembolic disease.
- Read the transplanted lung - integrate time since transplant and immunosuppression with the halo sign, the air-crescent sign, and the Pneumocystis pattern.
- Report it so the team can act - a five-element structured template and a cross-referenced atlas that turn every chapter into a two-minute lookup.
