An objective and non-invasive method to assess the extent, severity, course and prognosis of @entity2132 ( @entity2132 ) of the gastrointestinal tract would be of great importance. As high-resolution ultrasonography (HRU) and @entity2996 ( @entity2996 ) are used in inflammatory and @entity29 , we introduced these techniques to evaluate acute intestinal GvHD. In this study, 12 @entity1 with suspected intestinal and/or severe cutaneous @entity2132 were investigated by HRU and @entity2996 . The structure and thickness of the bowel wall and the blood flow pattern in the @entity6029 ( @entity6029 ) as well as in the bowel wall were evaluated. All @entity1 showed thickened bowel wall segments, especially in the ileocaecal region. Even in @entity1 without any clinical signs of intestinal involvement (3/12), sonographic changes were observed. In six @entity1 with severe @entity294 , sonographic signs of @entity294 were observed. In 4/12 @entity1 , an increased arterial blood flow in the bowel wall was demonstrated as a typical characteristic of an inflammatory bowel process. In contrast, in 4/12 @entity1 , ischaemic bowel wall lesions with high-resistance flow pattern in the @entity6029 were found. These @entity1 did not respond to immunosuppressive therapy and died. In conclusion, HRU is a useful tool for detecting @entity697 even before clinical symptoms. Moreover, HRU and @entity2996 can be applied to define the severity of @entity2132 and to identify @entity1 with a poor prognosis.
