Interstitial lung disease
Interstitial lung disease (ILD) is an umbrella term that encompasses a large number of disorders that are characterized by diffuse cellular infiltrates in a periacinar location.
Interstitial lung diseases classically produce the “3Cs”: cough, clubbing of the nails, and coarse crackles on auscultation
High-resolution CT (HRCT) of the chest, also referred to as HRCT chest or HRCT of the lungs, refers to a CT technique in which thin-slice chest images are obtained and post-processed in a high-spatial-frequency reconstruction algorithm. This technique obtains images with exquisite lung detail, which are ideal for the assessment of diffuse interstitial lung disease. A full HRCT protocol usually includes additional acquisitions:
•Expiratory images
•Prone images
