Sequential chest HRCT examinations were performed. Stage C to E. The total CT score of lung involvement was significantly higher in Stage C than in Stages

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.

In 5 to 10% of patients the chest radiograph is normal. Interstitial lung disease is a broad term for a number of diseases that lead to inflammation or scarring of the lungs, leading to fibrosis. 27 28 These diseases may be acute or chronic and have a variety of underlying causes, including infection, exposure to dust or other particles, or an underlying genetic predisposition. 5 27 HRCT - kriterier för UIP UIP–mönster: fyra kriterier uppfyllda • Perifer, basal dominans • Retikulära förändringar • Honeycombing med / utan traktionsbronkiektasier • Avsaknad av fynd som talar mot UIP Möjlig UIP: tre kriterier uppfyllda • Perifer, basal dominans • Retikulära förändringar 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.

The accurate interpretation of high-resolution computed tomography (HRCT) images requires a detailed understanding of normal lung anatomy, normal variations, normal findings that may mimic an abnormality (1,2) and the pathologic alterations in normal lung anatomy occurring in the presence of disease (1 –7). An increase in lung opacity, discernible on plain radiographs or HRCT, that results in obscuration of underlying vessels (Figs. 23-2, 23-12, and 23-13). This finding usually indicates the replacement of alveolar air or filling of airspaces by fluid, cells, or tissue, but can also be seen with extensive interstitial disease.

The technique of HRCT involves use of 1-2-mm-thick collimation scans with a high spatial frequency algorithm. HRCT scans performed during or after expiration to diagnose air trapping in patients who have obstructive lung disease (15,17,20,22). Scans can be obtained after expiration, can be gated to spirometry ( 49 – 51 ), or can be obtained dynamically during forced expiration ( 15 , 20 , 44 ).

High-resolution computed tomography (HRCT) is a method of examination which is more precise than chest 2-rat in the diagnosis and monitoring of diseases of the lung tissue and the airways. Modern CT equipment enables a volume HRCT scan covering the whole lung tissue. The HRCT appearance of pulmonary sarcoidosis varies greatly and is known to mimic many other diffuse infiltrative lung diseases.

A lung scan is a procedure that uses nuclear radiology to assess the function and structure of the lungs. It is most often performed when problems with the lungs and respiratory tract are suspected.

Basic HRCT patterns of lung disease Numerous studies and clinical experience have convincingly shown the superiority of high-resolution computed tomography (HRCT) over chest radiography in terms of improved detection of diffuse lung disease, the provision of a histospecific diagnosis, and the assessment of disease reversibility.

Farmer's lung is the best-known HP syndrome and results from the inhalation of fungal organisms that grow in moist hay or exposure to birds as pets (1). Although the position of HRCT as the dominant imaging technique for interstitial lung disease has remained unchallenged since its introduction in the late 1980s, the roles assumed by HRCT have undergone a steady evolution. This evolution has occurred in stages.
