Problems and Pitfalls of Gastrointestinal Endoscopy. Is There Still a Role for the Barium Meal?, mainly performed as single contrast studies, and the lack of competition resulted in few studies of accuracy or efficacy. The onset of endoscopy acted as a spur to the development of more sophisticated techniques, particularly double contrast or multiphasic studies, and at the same time contrast st

CT of the Stomach,ct evidence of mural and extra gastric lesions. Computed tomography (CT) is of course excellent at demonstrating the latter, but an emerging role in the evaluation of mucosal lesions has become evident. This will accelerate with multi-slice CT and perhaps virtual gastroscopy (.). To date the major r

Multislice CT of the Stomach,sible and allows for high-quality multiplanar reformations and 3D visualization. Adequate distension of the stomach using water as a negative contrast agent (hydro-CT) is a prerequisite for assessing the stomach wall. While such techniques have already been used with single-slice spiral CT to improv

Magnetic Resonance Imaging of the Stomach,. Only a few groups have shown interest in this topic, as conventional MRI of the stomach does not provide the image resolution of small areas of interest that is needed for the depiction of gastric wall pathology. However, the use of surface coils has improved the signal-to-noise ratios, consequent

CT of the Duodenum,ows direct imaging of the intestinal wall, secondary signs of bowel disease within the surrounding mesentery, and abnormal findings in adjacent structures (.). In clinical practice and in the radiological literature, most emphasis is placed on CT imaging of the colon, the stomach, and the distal sma
