Knowledge of the lung anatomy is essential for understanding HRCT. The interpretation of interstitial lung diseases is based on the type of involvement of the secondary lobule. The secondary lobule is the basic anatomic unit of pulmonary structure and function. It is the smallest lung unit that is surrounded by connective tissue septa.

Part of the highly regarded Specialty Imaging series, this fully updated second edition by Drs. Santiago Martínez-Jiménez, Melissa L. Rosado-de-Christenson, and Brett W. Carter, reflects the many recent changes in HRCT diagnostic interpretation. An easy-to-read bulleted format and state of the art imaging examples guide you step-by-step through every aspect of thin-section CT and HRCT in the

HRCT is used for diagnosis and assessment of interstitial lung disease, such as pulmonary fibrosis, and other generalized lung diseases such as emphysema and bronchiectasis. Applications [ edit ] Airways diseases, such as emphysema or bronchiolitis obliterans , cause air trapping on expiration, even though they may cause only minor changes to lung structure in their early stages. HRCT of the Lung: Anatomic Basis, Imaging Features, Differential Diagnosis is written to demonstrate the contributions of high-resolution CT (HRCT) to the interpretation of chest radiographic abnormalities and provide keys to the characterization of disease processes. The main objective of HRCT is to detect, characterize, and determine the extent of diseases that involve the lung parenchyma and airways. HRCT is the use of thin-section CT images (≤1.5-mm slice thickness) with a high spatial frequency reconstruction rheumatoid lung nodules; Plain radiograph. Chest radiograph may show: pleural effusion; lower zone predominant reticular or reticulonodular pattern; volume loss in advanced disease; skeletal changes, e.g. erosion of clavicles, glenohumeral erosive arthropathy, superior rib notching; CT. Chest CT or HRCT features include: pleural thickening or effusion Se hela listan på radiopaedia.org Knowledge of the lung anatomy is essential for understanding HRCT.

The CXR in affected individuals is often normal or shows non specific findings. A practical approach to cystic lung disease on HRCT Peter Beddy & Judith Babar & Anand Devaraj Received: 29 August 2010 /Revised: 18 October 2010 /Accepted: 21 October 2010 /Published online: 12 November 2010 # European Society of Radiology 2010 Abstract A lung cyst is defined as a round parenchymal lucency or area of low attenuation with a Honeycombing Honeycomb lung remodeling (honeycombing) reflects the end stage of a number of diseases that cause parenchymal destruction. It presents a characteristic HRCT pattern, with subpleural, thick- walled cysts that share walls and, when advanced, are often stacked in multiple layers (Figure 6).

Large vessel vasculitides can also affect the lung and pulmonary vessels: Takayasu arteritis: 50-80% pulmonary involvement 1; giant cell arteritis; Behçet disease: 1-8% thoracic involvement 1; Hugh Stovin syndrome; Granulomatous disease The HRCT appearance of pulmonary sarcoidosis varies greatly and is known to mimic many other diffuse infiltrative lung diseases. Approximately 60 to 70% of patients with sarcoidosis have characteristic radiologic findings. In 25 to 30% of cases the radiologic findings are atypical.
