We compared images obtained during gastrointestinal fluoroscopy by specially trained and experienced technologists with those obtained by radiology residents to determine if the quality of images was similar between the two groups.
Three senior radiologists examined the fluoroscopic spot films of 80 patients who were divided evenly into four groups: barium enemas performed by technologists, barium enemas performed by residents, gastrointestinal series performed by technologists, and gastrointestinal series performed by residents. The senior radiologists graded adequacy of visualization of the esophagus, stomach, duodenum, and all parts of the colon. A grade of 1 was given for poor films, 2 for adequate films, and 3 for good films. They did not know who performed each study.
For barium enemas, the residents' mean score was slightly higher than that of the technologists (13.5 compared with 12.9). For gastrointestinal series, residents' mean score was again slightly higher (20.5 compared with 19.7). In neither case did the difference reach statistical significance.
Fluoroscopic films obtained by residents and by specially trained and experienced technologists for barium enemas or gastrointestinal series were statistically indistinguishable.
我们将经过专门培训且经验丰富的技术人员在胃肠道荧光镜检查期间获得的图像与放射科住院医师获得的图像进行比较，以确定两组图像质量是否相似。
三位资深放射科医生检查了80例患者的荧光透视点片，这些患者被平均分为四组：技术人员进行的钡灌肠、住院医师进行的钡灌肠、技术人员进行的胃肠道造影以及住院医师进行的胃肠道造影。资深放射科医生对食管、胃、十二指肠和结肠各部位的显影充分程度进行评分。差的片子评为1分，合格的片子评为2分，好的片子评为3分。他们不知道每项检查是谁做的。
对于钡灌肠，住院医师的平均得分略高于技术人员（分别为13.5分和12.9分）。对于胃肠道造影，住院医师的平均得分同样略高（分别为20.5分和19.7分）。在这两种情况下，差异均未达到统计学显著性。
住院医师以及经过专门培训且经验丰富的技术人员在钡灌肠或胃肠道造影时获得的荧光透视片在统计学上无显著差异。
