Esophagus I: anatomy, rings, inflammation; Esophagus II: Strictures, Acute syndromes, Neoplasms and Vascular impressions; HRCT. Basic Interpretation HRCT chest is very sensitive and accurate in picking up lung parenchymal abnormalities in laboratory negative RT-PCR cases with high clinical suspicion of COVID-19 infection and also in all symptomatic patients where RT-PCR was not done. Expiratory high-resolution CT (HRCT) imaging corresponds to an additional CT acquisition performed as part of the HRCT chest protocol. It represents a scan performed with the patient on supine and images obtained at the end-expiration. HRCT Technique Maximize spatial resolution thin collimation high spatial algorithm Advantages over chest x-ray no summation high contrast There is no magic with HRCT. The basic premise is simple, maximize spatial resolution by using the thinnest collimation and a high spatial frequency algorithm. This use to be 1.5 mm.

On the left we see a chest film with a typical finger-in-glove shadow. The HRCT shows focal bronchiectasis with extensive mucoid impaction, which is in the appropriate clinical setting (asthma and serum eosinophilia) typical for Allergic bronchopulmonary aspergillosis (ABPA).

Globally, high resolution computed tomography (HRCT) chest is currently underutilized for the evaluation and management of patients affected with COVID-19. HRCT is used in many developed countries for severe cases of COVID pneumonia primarily to assess the status of the lung and not in the clinical context of treating the patients.

As the technique calls for 1-2 mm slice thickness, it only samples 20-25% of the chest, therefore, HRCT is not suitable for focal diseases such as lung cancer. This limitation has partially been addressed by the introduction of volume imaging UIP. Predominantly subpleural and basal.
