Imaging studies that aid in the diagnosis of gastric cancer in patients in whom the disease is suggested clinically include the following:

  • Esophagogastroduodenoscopy (EGD): To evaluate gastric wall and lymph node involvement
  • Double-contrast upper GI series and barium swallows: May be helpful in delineating the extent of disease when obstructive symptoms are present or when bulky proximal tumors prevent passage of the endoscope to examine the stomach distal to an obstruction
  • Chest radiography: To evaluate for metastatic lesions
  • CT scanning or MRI of the chest, abdomen, and pelvis: To assess the local disease process and evaluate potential areas of spread
  • Endoscopic ultrasonography (EUS): Staging tool for more precise preoperative assessment of the tumor stage
