Noncontrast chest CT lung window images in a 42-year-old male participant with normal lungs

Caption

Axial noncontrast chest CT lung window images in a 42-year-old male participant with normal lungs. (A) Normal-dose CT, (B) ultra-low-dose CT (ULDCT), and (C) denoised ULDCT images. Normal lungs were observed on normal-dose CT image. However, due to inherent image noise at ULDCT, the lung pattern was falsely classified as positive viral infection by both readers. The denoising technique of the denoised ULDCT corrected this artifact, and the participant was correctly categorized as having no infection.
