Early diagnosis of tumors of the small intestine is a challenge for clinicians and for
radiologists. The detection of tumors of the small intestine is a field in which the video
capsule endoscopy has the lowest performance.
The entero-CT with enteroclysis is the imaging technique used primarily to explore patients
with a strong suspicion of small intestine tumors. However the entero-CT with enteroclysis
has disadvantages : it is irradiating, the nasojejunal tube implies a discomfort to the
patient and it is a complicated examination in terms of logistics with necessity of specific
equipment to insert the nasojejunal tube.
MRI has been proposed as an alternative imaging technique and satisfactory results have been
reported with the MRI enteroclysis. However, this technique has several disadvantages related
to nasojejunal tube insertion and the necessity of equipment compatible with the high
magnetic fields. The enterography-MRI without enteroclysis, whose principle is to distend the
small intestine by ingestion of large quantities of a liquid, has a major and undisputed role
in the exploration of Crohn's disease of the small bowel. However, its capacity for
distension of the small intestine for optimal tumor detection is questioned and its role in
tumor detection is largely unknown.
