摘要
【目的】探讨数字化X线摄影(DR:Digital Radiography)中双能量减影(The dual-energy subtrac-tion)技术在胸部X线检查中的应用价值。【方法】搜集20份胸部DES为阳性病例的影像,然后对每一病例的DES图像和DR图像的病灶显示能力,病灶定位定性能力进行比较。【结果】DES图像发现细微骨病变,肺内结节性病灶及对病灶的定位定性优于DR图像。【结论】DES能分别观察胸部软组织和骨骼,合理选用DES,能提供更多的影像诊断信息,是普通胸部X线检查有益的补充。
[Objective]To evaluate the clinical practical value of dual - energy subtraction (DES) on chest digital radiography(DR). [Methods]DES images of twenty cases with positive chest DR findings were collected, the DES images were compared with regular DR images to evaluate the capability of DES images in lesion detection,localization and differentiation. [Results]DES images were superior to regular DR images in detecting minute bony lesions, intrapulmonary nodular lesions and in lesion localiztion. [Conclusion] DES is capable of visualizing the soft tissue and bony tissues on the chest images separately. Rational selection of the DES in chest digital radiography may provide more useful information than regular DR images. It may be considered as the supplement to regular chest DR.
