Fig. 1A. 52-year-old man with colon cancer and multiple pulmonary metastatic
nodules. Selenium-based (A) and storage phosphor (B) images show
unobscured retrocardiac and subdiaphragmatic lung. Note multiple nodules and
linear opacities.

Fig. 3A. 42-year-old man with lung cancer and malignant pleural effusion.
Selenium-based (A) and storage phosphor (B) images show
unobscured lung, hilum, and ribs. Sharp right minor fissure is seen on
selenium-based image; fissure is obscured on storage phosphor image. Although
this difference may be caused by minor position difference of patients, images
were evaluated as they appeared.
