Core Tip
Core tip: Endoscopic ultrasonography (EUS) and computed tomography (CT) have been used as the diagnostic modality of choice in preoperative staging of gastric cancer. Magnetic resonance imaging (MRI) and (18F) 2-Fluoro-2-deoxyglucose (FDG) positron emission tomography (PET) were also employed. The purpose of this article is to provide concisely summarized information in preoperative staging of EUS, multi-detector row CT (MDCT), MRI and PET for gastric cancer. In T staging, both EUS and MDCT show high accuracy. In N staging, the diagnostic accuracy of EUS, MDCT and MRI is not sufficient, but the specificity of FDG-PET was the highest among the modalities.
