The usefulness of full-size radiographs obtained with the overhead tube following fluoroscopy was evaluated based on an analysis of 306 biphasic upper gastrointestinal studies that included follow-up postfluoroscopy views. In 32 studies with abnormal findings, the postfluoroscopy images were normal. In one case, the postfluoroscopy images revealed an abnormality not seen on spot views. The confidence levels rose in only 19 cases (6.2%) when postfluoroscopy images were used. In the appropriate setting, routine postfluoroscopy views after an upper gastrointestinal series are of little value. Nonetheless, in a teaching hospital, these images should be obtained when fluoroscopy is performed by junior residents.
通过对306例双相上消化道造影检查（包括透视后随访影像）进行分析，评估了透视后使用高架管获得的全尺寸X光片的实用性。在32例有异常发现的检查中，透视后影像正常。在1例中，透视后影像显示出点片上未发现的异常。使用透视后影像时，信心水平仅在19例（6.2%）中有所提高。在适当的情况下，上消化道造影系列检查后的常规透视后影像价值不大。尽管如此，在教学医院，当由初级住院医师进行透视时，应获取这些影像。
