摘　　要：目的：探讨数字化综合Ｘ线机及激光照像机进行胃肠道造影检查的临床应用价值。材料和方法：５０例病人在同一台Ｘ线机上同时进行了普通Ｘ线胃肠双对比造影和应用数字化Ｘ线机图像后处理胃肠双对比造影，对图像进行分析比较。结果：普通Ｘ线机胃肠造影因受呼吸运动、病人转动影响及ｋＶ、ｍＡｓ等条件选择不当等影响，致１２例照片质量欠佳；而所有数字化成像激光打印图像清晰度、灰度、对比度均佳，细微结构显示清晰，并可动态观察胃肠道功能。结论：数字化成像胃肠双对比造影激光打印图像质量好，工作效率高，资料便于储存。Purpose:ToinvestigatetheclinicaleficacyofdigitalX-rayimagingcombinedwithlasercamerasystemindoublecontrastexaminationofgastrointestinaltract.Materialsandmethods:Fiftypatientsaccepteddouble-contrastexaminationofgastrointestinaltractonthesameX-rayma-chineusingbothconventionalanddigitalX-rayimaging.Theimagingsofbothtechniqueswereanal-ysedandcompared.Results:Theimagesof12patientswithconventionaltechniquewerenotsatis-factorybecauseofrespiratorymovement,uncooperativepatientandimpropersettingofradiographicparameterssuchaskVandmAs.Aldigitalimageswereexcelentintermsofsharpnessandcon-trast;besides,gastrointestinaldynamicfunctioncouldalsobestudiedifnecessary.Conclusion:Digi-talX-rayimagingcombinedwithlasercamerasystemcanyieldhigh-qualityimages,withhighpro-ductivityandthecapabilityofstoringtheimages,itsclinicalapplicationindouble-contrastexamina-tionofgastrointestinaltractispromising.
