Prognosis and treatment of gastroesophageal cancer depends on an accurate preoperative staging of tumors. Imaging modalities normally used in clinical staging are esophagography, esophagoscopy, endoscopic ultrasonography, computed tomography and positron emission tomography. The aim of this article was to review the literature regarding the performance of each of these imaging modalities. The use of oral and intravenous contrast will be discussed. The role of computed tomography with peroral and intravenous contrast enhancement was emphasized in cases when a masslike density was seen at the GE junction.
