[Single exposure energy subtraction chest radiography--clinical survey on utility of bone image].
The authors undertook a clinical study to determine the values and limitations of soft tissue subtracted image by dual-energy digital radiography. 573 patients were examined by dual-energy subtraction with a single exposure using computed radiography. Soft tissue subtracted image were found informative in 37 patients (6.5%) compared with non-subtraction image. It provided useful information about demonstrating calcification in pulmonary nodules, assessing the presence or absence of rib lesions, and excluding the possibility of pulmonary nodules.
