title: Imaging of various gastric lesions with 2D MPR and CT gastrography performed with multidetector CT.
abstract: Recent advances in computed tomographic (CT) technology, three-dimensional imaging software, and cheaper data storage capacity have made faster, simpler, and more accurate gastric imaging available. Two-dimensional multiplanar reformation and CT gastrography including virtual gastroscopy and transparency rendering allow multiplanar cross-sectional imaging, gastroscopic viewing, and upper gastrointestinal series imaging in the same data acquisition. Multi-detector row CT allows noninvasive assessment of the gastric wall and the perigastric extent of disease. It is also helpful in detection and evaluation of gastric malignancies and a variety of inflammatory conditions that affect the stomach. Conventional gastroscopy provides the most useful information about the exact location of the lesion and also allows performance of biopsy. Endoscopic ultrasonography (US) provides the most useful information about horizontal extension of the tumor, the depth of mural invasion, and perigastric lymphadenopathy. However, endoscopic US has not been able to replace CT for tumor staging because of its limitations in demonstrating distant lymphadenopathy or metastatic deposits.
