数字化影像系统及三种测量方法在排粪造影中的应用价值

目的：探讨利用两种数字化X线影像系统及三种测量方法在排粪造影中的应用价值。方法：选择数字化X线摄像系统及数字化胃肠诊断系统为467位排粪障碍者行排粪造影检查。A组：四合一缩放尺测量法，B组：量角尺加分规比对参照标尺测量法，C组：机上直接数字化测量方法。煞果：排粪造影471例；A组136例，测量异常133例（97．80％）；B组153例，测量异常148例（96．73％）；C组182例，测量异常179例（98．36％）。结论：利用两种数字化影像系统及三种测量方法行排粪造影检查，异常检出率平均达到97．63％，均可为肛、直肠功能性改变的临床诊治提供准确的数字化影像学依据。

The application values of digitalized-imaging system and three measuring methods in defecography

Objective To study the application values of two digtalized-imaging systems and three measuring methods in defecography. Method Total 467 patients with defected dysfunction underwent digitalized X-ray system,digitalized gastrointestinal diagnostic system in defecographic examination.The following measuring methods were used:group A:one in four pattern maker's rule;group B:angle rule plus compasses;group C:measurement directly by computer.Results Total 467 drfecography cases were determined.In group A there were abnormality of 133 cases in 136 cases.In group B,there were abnormality of 148 cases in 153 cases and in group C there were abnormality of 179 cases in 182 cases.Conclusion For pathological changes in anorectal,two digitalized-imaging systems and three measuring methods are applied for defecography and the average abnormality rate is 97.63%which precisely digitalized data for the clinical treatment.
