Abstract:
Objective To evaluate the clinical value of dual-energy subtraction digital radiography in diagnosing the pulmonary nodulesand calification in nodules.Methods Using American GE Revolutln DR-XR systems,All 80 patients were examined by dual-energy.Tissus images、bone images and the original digital radiographic images were obtained.Dual-energy digital subtraction images were compared with the original digital radiographic images.Results Of 186 pulmonary nodules proved by CT,126(94 uncalified and 32 calified)were detected by tissues images and bone images and 109(83 uncalified and 26 calified)were detected by the original digital radiographic images.Conclusion Dual-energy subtraction imaging is superior to the original digital radiographic images in detection of pulmonary nodules and calification in a nodule.Dual-energy subtraction images can act as a complement for the original digital radiographic images.
