Common … WebIt has been suggested that radiation doses due to high-resolution computed tomography (HRCT) of the chest are considerably higher than those from conventional CT. We compared the effective dose (E, mSv) in conventional chest CT (10-mm contiguous slices) and HRCT (1.5-mm slices, gap 10 mm). In our st … 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 HRCT may be used to evaluate extent of disease, monitor treatment response, and select … See more HRCT is performed in order to visualize small structures of the lung and detect subtle changes of disease that otherwise may be difficult to assess on conventional chest imaging 3. … See more HRCT was historically developed to improve spatial resolution in the era of the first-generation scanners (sequential image acquisition … See more The term ''high-resolution computed tomography'' was first used by Todo et al. in 1982.
