| 摘 要： | 目的: 探讨双能量减影软组织像检出肺小结节的价值.材料和方法: 对84例X线胸片发现肺小结节的患者进行DDR-DE和MSCT的检查.结果: 84例肺小结节检出情况: 胸片196个,DDR-DE软组织像157个,MSCT 160个.DDR-DE与胸片相比排除肺小结节55个、增加肺小结节16个.其中排除肺小结节17例,增加肺小结节数12例,减少肺小结节数16例.MSCT与DDR-DE相比排除肺小结节6个,增加肺小结节9个.结论: DDR-DE软组织像比X线胸片明显提高肺小结节的检出率,减少了误诊. |

| Abstract: | Purpose: To evaluate the value in detecting pulmonary nodules(PNs) on soft imaging of dual-energy subtraction(DE) with direct digital radiography(DDR). Materials and Methods: 84 cases of PNs on X-ray chest imaging were processed dual-energy subtraction with direct digital radiography and MSCT. Results: 196 PNs were detected in X-ray chest imaging of 84 cases. 157 PNs were detected in DDR-DE and 160 PNs were detected in MSCT.Compared DDR-DE and X-ray film: eliminated 39 PNs and increased 16 PNs on soft imaging of 84 cases: 17 cases eliminated PNs, 12 cases increased the number of PNs and 16 cases reduced the number of PNs. Compared MSCT and DDR-DE : eliminated 6 PNs and increased 9 PNs. Conclusion: Soft imaging of dual-energy subtraction with direct digital radiography can significantly improve the correct diagnostic rate of pulmonary nodules and reduce misdiagnostic rate. |
