目的:探讨数字摄影(DR)的双能量减影(DE)技术对鼻咽部至主支气管呼吸气道病变的诊断价值。方法:对35例临床症状典型的患者进行DE检查,并与常规平片图像作对比分析。结果:DE技术对气道病变影像显示明显优于普通DR检查。结论:DE技术有效地去除骨组织的影响,获得单纯的软组织图像,经DR后处理技术让病变影像显示,能提高常规检查对呼吸气道病变的诊断能力。
Objective: To investigate the diagnostic value of dual energy subtraction (DE) technique of digital photography (DR) for respiratory tract pathology of nasopharynx to main bronchus. Methods: Thirty-five patients with typical clinical symptoms were examined by DE and compared with conventional plain radiographs. Results: The DE technique was superior to ordinary DR in imaging the airway lesions. Conclusion: DE technique can effectively remove the influence of bone tissue and obtain pure soft tissue images. DR technique can be used to display the lesion images, which can improve the ability of routine examination to diagnose respiratory tract diseases.
