  • Abstract
  • Look Inside

 Small mucosal lesions of the small intestine can be clearly demonstrated by the double contrast method except in the terminal ileum. But mucosal lesions in the terminal ileum are clearly demonstrated by the compressed method or the retrograde air injection technique. Fast MR imaging techniques, including half-Fourier acquisition single-shot turbo spin-echo (HASTE), produce high-quality images of the abdomen in seconds. These MR imagings clearly detect swelling of the intestinal wall or intestinal obstruction. However, in these MR imagings, small mucosal lesions can not be demonstrated. Therefore, in differential diagnosis of small intestinal diseases we should detect mucosal lesions by the double contrast method. In a patient with superior mesenteric and portal vein thrombosis, the involved segment had an inner wall of low signal intensity and a high-signal-intensity outer wall. In a patient with arterial thrombosis, the signal intensity of the thickened intestinal wall was less than that of fat but slightly greater than that of muscle.
