A, an example of a COVID‐19 confirmed case showing pleural thickening and irregularity with presence of focal B‐lines. Quantitative pleural line features detected the case accurately as COVID‐19, whereas TLT features incorrectly identified the case as normal. B, an example of a normal lung image showing a thin and well‐defined pleural line and A‐lines. Quantitative pleural line features detected the case accurately as normal whereas TLT features incorrectly identified the case as COVID‐19. COVID‐19, coronavirus disease 2019; TLT, traditional lung texture
