Esophageal radionuclide transit testing is a sensitive technique for assessing esophageal clearance. Experience with the technique in 150 patients has led to an awareness of several pitfalls which might lead to false-positive results. Potential problems may be grouped into technical factors, clinical aspects, and misinterpretations. Examples of these are presented and techniques to minimize such problems are discussed.
