In 1985, Naidich et al., Nakata et al., and Zerhouni et al. This technique obtains images with exquisite lung detail, which are ideal for the assessment of diffuse interstitial lung disease. These signs are mainly seen in patients with early disease and mild symptoms of COVID-19 pneumonia, which may be due to infection resulting in alveolar swelling, small exudation of the alveolar cavity, and inflammation of the alveolar space, caused increased lung density (18).

HRCT is particularly useful in the assessment of diffuse lung conditions involving the interstitium such as: 1. interstitial lung disease 2. cystic lung disease 3. small airways disease 4. pulmonary micronodules 5. bronchiectasis Uninformed referrals commonly request for a "high-resolution" CT of the chest with the notion that HRCT represents a better version of a "standard" CT chest, however this is a misconception. doi: 10.1101/2020.03.06.20032417, 16.
