Radiological imaging of small-bowel tumors

While diagnosis of small-bowel tumors is clinically difficult, imaging examinations have a great role in it. Small-bowel enteroclysis allows viewing of the entire small-bowel for evaluating tumor location, size, and shape. CT gives information on both the intra- and extraluminal features of small-bowel tumors, mesenteric abnormalities, and distant organ spread. Multidetector-row computed tomography (MDCT) has improved image quality and reduced scan times. Furthermore, CT enteroclysis using MDCT with adequate visceral distension allows good visualization of small-bowel tumors. It is very important for clinicians to know the characteristic imaging findings of small-bowel tumors, although they are rare.
