Overview

• Today’s Radiology publication introduces a multisociety consensus on best practices for CT imaging of post-COVID-19 residual lung abnormalities
• The guidelines advise chest CT for patients with persistent or worsening respiratory symptoms three months after infection and set criteria for follow-up timing
• Recommendations stress low-dose CT protocols aligned with ALARA principles to minimize radiation during serial evaluations
• The statement endorses the term “post-COVID-19 residual lung abnormalities” to distinguish non-progressive, stabilizing findings from interstitial lung disease or fibrosis
• Developed through a two-stage Delphi process with 21 chest radiologists and reviewed by pulmonologists, the recommendations aim to harmonize practice across 14 countries
