A survey of 45 radiologists with a special interest in gastrointestinal radiology showed that only 8% used a preliminary abdominal film for oral cholecystography. Review of 467 cases of oral cholecystography with preliminary films over a 1 year period disclosed 88 confirmed cases of cholelithiasis. Of these 88 cases, 27% had opaque gallstones visible on the preliminary film. In one-third of the cases, the opaque gallstones had a classic diagnostic appearance, while the remainder required oral cholecystography for confirmation. Opaque calculi were obscured by oral contrast material in 2% of cases. Other significant pathology on the preliminary films was found in 5.5% of the 467 cases.
一项针对45名对胃肠放射学有特殊兴趣的放射科医生的调查显示，只有8%的人在口服胆囊造影时使用初步腹部平片。对1年内467例有初步平片的口服胆囊造影病例进行回顾，发现88例确诊为胆结石。在这88例病例中，27%在初步平片上可见不透光胆结石。在三分之一的病例中，不透光胆结石具有典型的诊断表现，而其余病例则需要口服胆囊造影来确诊。2%的病例中，不透光结石被口服造影剂遮挡。在467例病例中的5.5%的初步平片上发现了其他重要病变。
