Medical imaging is an essential part of the diagnostic workup of many gastrointestinal disorders. This paper reviews imaging and endoscopy of gastric tumors in dogs and cats and the techniques used. The appearance of the normal as well as the various aspects of gastric tumors are described for these different modalities. Plain radiography is widely available but has limited diagnostic value. Contrast radiography has higher sensitivity but is laborious and time-consuming. Ultrasonography (if an adequate acoustic window is available), endosonography and endoscopy are the most appropriate modalities for diagnosing gastric tumors. They are especially useful when obtaining samples for cytologic or histopathologic examination, because the imaging modalities do not always differentiate between infl ammatory or infectious conditions and neoplastic disorders. Hydro-helical CT was found helpful for evaluating the location and local invasive-ness of the lesion. Ultrasonography and endoscopy are useful modalities for taking adequate biopsies.
