2. Figure 1
(A–D) A 24-year-old man with RA. (A) Transaxial image shows doubling of vessels and bronchial walls in both lungs (arrows). (B) Sagittal reformatted image clearly shows the stair-step artifact at the same anatomical level of (A) (arrows). (C) Transaxial image at the same anatomical level of (A) shows severe blurring of the left anterior descending coronary artery (arrow). (D) Curved planar reconstructed image shows unevaluable segment in the mid left anterior descending coronary artery because of respiratory artifact.
