THE UPPER gastrointestinal (UGI) series is a roentgenographic screening examination of the UGI tract for patients exhibiting a wide variety of clinical symptoms and signs. The findings on the UGI series often determine the need for further evaluative procedures. The clinician is well aware that many diseases of the stomach can manifest the same symptoms; he must also realize they can demonstrate identical roentgenographic findings on the UGI series. If an irregular polypoid or an infiltrating lesion of the stomach is demonstrated on the UGI series, the radiologist naturally considers malignant neoplasms as the most likely diagnosis. But he also must remember that benign processes in the stomach can grossly simulate malignant neoplasms and that they, too, must always be considered in the differential diagnosis. The diagnoses made by the radiologist on the basis of gross roentgenographic findings are, in effect, predictions based on statistical probabilities.
