Fig. 3C. —Synopsis of images reconstructed from nongated (A, C,
E) and ECG-gated (B, D, F) MDCT data of 58-year-old woman with no
bronchial abnormality. Volume-rendered images obtained using nongated data
(C) show fewer artifacts in lung parenchyma (arrows, D)
compared to volume rendering using ECG-gated technique (D). Stairstep
artifacts of carina were more pronounced in ECG-gated series
(arrowhead, D). Artifacts in lung parenchyma are located in
density range between –900 and –1,000 H, which is crucial for
discriminating air-filled lung from peripheral bronchi.
