“…The introduction of neutral oral contrast agents with improved luminal distention and advances in CT technology have converged to provide new CT imaging techniques specific for the small bowel known as CT enterography and CT enteroclysis. Whereas in CT enterography luminal distention is achieved by ingestion (11), in CT enteroclysis contrast medium is administered into the small intestine through a nasojejunal tube under fluoroscopic guidance (12).…”

“…After a 6-hour fast, patients are given a total of 1200-1600 mL of neutral oral contrast agent, either through a tube at a rate of 60-120 mL/min (CT enteroclysis) or divided into four oral doses given every 20 minutes, beginning 60 minutes before scanning; the last dose is administered with the patient on the CT table just before scanning (CT enterography). Intravenous administration of a spasmolytic drug is essential before image acquisition to minimize patient discomfort and bowel motion artifact (11)(12)(13).…”

Gastrointestinal (GI) bleeding is a common clinical condition that is increasingly seen in an aging population and frequently requires hospitalization and intervention, with significant morbidity and mortality. Obscure GI bleeding (OGIB) is defined as loss of blood with no source identified after upper endoscopy and colonoscopy. Whether an obscure site of bleeding is clinically evident or silent, it constitutes a diagnostic and therapeutic challenge for the clinician. Gastroenterology and radiology provide the essential diagnostic tools used to evaluate suspected OGIB, each with its strengths and weaknesses. Small bowel series and conventional enteroclysis have a limited role in OGIB. Computed tomographic (CT) enterography and CT enteroclysis are noninvasive techniques with promising results in evaluation of small bowel disease and silent OGIB. CT angiography is a useful triaging tool for diagnosing or excluding active GI hemorrhage, localizing the site of bleeding, and guiding subsequent treatment. Tagged red blood cell scanning is the most sensitive technique for detection of active GI bleeding and allows imaging over a prolonged period, making it useful for detecting intermittent bleeding. Capsule endoscopy has emerged as an important tool for investigating OGIB, but it may soon have competition from double-balloon enteroscopy, a diagnostic technique that can also facilitate therapy.

“…In recent study of 56 patients with known Crohn's disease, CTEc and wireless capsule enteroscopy (WCE) both depicted a substantial number of terminal ileal Crohn's lesions (24 with WCE vs 21 with CTEc), unlike those for jejunal lesions (25 with WCE vs 12 with CTEc) 17 . CTEc has been of value in resolving the false-positive and falsenegative interpretations from nonenteral volume-challenged small-bowel studies that arise from the difficulties associated with poor distention or peristalsis, simulating wall thickening 18 . There are some disadvantages of CTEc -the discomfort associated with nasojejunal tube placement may be improved with the use of local sedation and smaller tubes.…”

“…CTE can also differentiate between outward growth and inward growth tumors, indicate whether the tumor is lobulated or whether there is internal necrosis, depict the depth of infiltration, and determine the types of pathological changes based on the general morphology of the tumors. Furthermore, it can also be used to identify metastasis over time using the entire abdominal scan, to make accurate preoperative staging, to design an appropriate treatment plan and to make a prognostic evaluation [8][9][10][11][12][13][14] . Conventional CT scans can show large intestinal tumors, however, they cannot provide accurate information about tumor infiltration in the intestinal wall.…”

“…CTE can accurately determine the number of small intestinal tumors and can be used to make early diagnosis of small intestinal tumors. Thus, CTE is the primary choice for the detection and localization of small intestinal tumors [13] . Boudiaf 's study [14] showed that CTE has a high sensitivity (100%) and specificity (95%) in the diagnosis of small intestinal tumors.…”

Precise examination and diagnosis of small intestinal tumors is difficult because of the curved course and overlapping canal of the small intestine. Traditional technology for intestinal canal examination and endoscopy cannot exhibit the intestinal wall and extra-luminal structure well. With the development and advancement of multi-slice spiral computed tomography and magnetic resonance imaging (MRI), computed tomography enteroclysis (CTE) and magnetic resonance enteroclysis (MRE) are widely used in the examination and diagnosis of small intestinal tumors. CTE and MRE, with three-dimensional imaging capabilities and excellent soft-tissue contrast, can analyze the abnormalities of peripheral intestinal structure as well as the tunica mucosa. In addition, these two technologies can clearly reveal the localization, appearance, degree of mesenteric infiltration and remote tumor metastasis, which increases our cognition of the imaging diagnosis for intestinal tumors. Here we review recent progress in imaging (CT and MRI) examination and diagnosis of small intestinal tumors.
