Conventional Radiography and DESR.
Conventional radiograph (CR, a). Bone image (b), and soft tissue image (c) of the chest after subtraction of thoracic skeletal structures.

Lung mass on different imaging modalities.
61 year old female patient showing a focal increase in density in the left upper lobe in the CR image (a). This focal increase in density is not visible on the bone image (b) while it is clearly depicted by the soft tissue image (c) and therefore is primarily suspicious for a soft tissue mass in the left upper lobe. CT (d) confirms the presence of a soft tissue mass in the left upper lobe adjacent to the aortic arch suspicious for a bronchus carcinoma.

Interstitial lung changes in different imaging modalities.
Appearance of interstitial lung changes such as (a) emphysema, (b) reticular lung changes, (c) nodular lung changes and (d) scarring of lung parenchyma with (I) CR, (II) DESR soft tissue image and (III) CT in four different patients. While nodular changes are visible in all the three imaging modalities (Ic, IIc and IIIc), emphysema, reticular lung changes and lung scarring are better depicted in the DESR soft tissue image (IIa, IIb and IId) compared to the CR image (Ia, Ib and Id). The patient having the emphysema had also a solid lung mass in the right lower lobe (Ia and IIa).
