Abstract:
Primary small bowel tumors have low incidence and contain predominantly solid components, and the lesions are similar and difficult to be detected and distinguished with multislice spiral CT (MSCT) plain scans. In this article we describe contrast-enhanced MSCT technique and imaging characteristics for solid small bowel tumors or small bowel tumors containing predominantly solid components, including the type and use of contrast agents. In contrast-enhanced MSCT, small bowel imaging with CT has the advantages of determining the true extent of intestinal wall lesions, the possible extent of wall penetration, the degree of mesenteric involvement, and distant metastases, as well as easiness to detect and identify the blood supply vessels of small bowel tumors and assessment of the corresponding complications. Contrast-enhanced MSCT has become the best noninvasive imaging technique for the diagnosis, evaluation, and staging of solid small bowel tumors or small bowel tumors containing predominantly solid components. CT texture analysis (CTTA) is a new research hotspot and can be useful for the correct diagnosis of primary small bowel tumors containing predominantly solid components.
