Imaging of small bowel tumors.

Small bowel tumors represent less than 25% of all gastrointestinal tumors and 1-2% of malignant tumors in general. However for their nonspecific clinical presentation, diagnosis is often late, because of the patient delay to contact the doctor and especially the doctor difficulty to advance the clinical suspicion and request the suitable clinicoinstrumental diagnostic tests. The radiologist plays a major role in early diagnosis, treatment and prognosis. In the last decade diagnostic imaging (US, CT, MRI) has supported conventional barium studies: the diagnostic accuracy has been enhanced in terms of identification, characterization and evaluation of the degree of severity of these diseases. The choice of the most suitable technique should be based on the diagnostic skills acquired in the field and on the awareness of the limits and indications of each method. In this article, the contribution of imaging to the diagnosis of small bowel tumors, is analyzed.
