Three physicians’ subjective ratings of Group A and Group B images.
Fig 1.
The right lung exhibits scattered patchy opacities, nodules, tree bud signs, and dot stripe patterns. Faint bronchial columnar changes are observed. Obvious respiratory movement artifacts are present. The volume of the left lung appears reduced.
Fig 2.
Mediastinal Window (120 kV Scan).
The left lung shows soft tissue density and a translucent area indicative of insect erosion. The left side of the heart and surrounding structures are visualized.
Fig 3.
Multiple scattered patchy opacities, small nodules, tree-in-bud opacities, and heterogeneous dot-like/linear densities are observed in the right lung. The lesion morphology remains consistent with that shown in Fig 1. Compared to Fig 1, bronchiectatic changes are distinctly visible within the bronchial architecture, and no significant respiratory motion artifacts are observed.
Fig 4.
Mediastinal windows (Sn100kV scan).
Leftward cardiac displacement is observed. The left lung demonstrates a soft-tissue density lesion containing moth-eaten lucent area. Image qquality remains comparable to that of Fig 2 in terms of anatomical delineation and artifact control.
