Core Tip

Core tip: Diagnostic imaging of gastric tumors remains a practical challenge. However, in some cases of uncommon gastric tumors and tumor-like lesions, there are some specific radiographic features. Using the multidetector computed tomography, with water as a negative oral contrast agent and intravenous contrast medium, can provide critical information for the diagnosis of gastric diseases. Familiarity with the computed tomography features of these diseases facilitates accurate diagnosis and further management.
