| 目的 通过对双能量减影(DES)与常规数字X线成像(CDR)对肠梗阻碘剂造影模型和肠梗阻患者的检测能力的比较,证明双能量减影在肠梗阻碘剂消化道造影检查有一定的应用价值。方法 制造肠梗阻碘剂造影模型,对模型和5例肠梗阻患者分别拍摄能量减影和常规DR,比较其密度分辨率。结果 能量减影检测出泛影葡胺的浓度可达0.593%,而常规DR仅为4.75%,能量减影可以探测出的浓度比常规DR能探出的低8倍。结论 能量减影可以去除软组织,气体等对造影剂的掩盖,对泛影葡胺浓度的检测能力明显优于常规DR,在肠梗阻碘剂消化道造影检查中具有良好的应用价值。 |

| Objective To prove dual energy subtraction(DES) is useful to iodine contrast in patients with ileus through comparing the performance of DES with that of CDR in detecting the iodine contrast model and patients of ileus. Methods The iodine contrast model of ileus was made. The model and 5 cases patients with ileus were examined by DES and CDR. Then their rates of density distinguish were compared. Results The 0.593% concentration can be examined by the DES uersus 4.75% by CDR, so DES can detect iodine eight times lower than CDR do. Conclusion DES is superior to CDR in detecting the iodine contrast model or patients of ileu, because DES can eliminate efficiently the influence of soft tissue and gas. There is good outlook for the application of DES in iodine contrast examination of patients with ileus. |
