“…Reflecting the multitude of these pathways, many substances have been evaluated for the purpose of serving as a gastrointestinal contrast agent [12,13,14,15,16,17,18,19,20,21,22,23]. Although most of these agents were designed to be taken orally, the majority of them can also be applied rectally.…”

Driven by the improvements in gradient technology, breathhold T1- and T2-weighted imaging of the abdominal structures has become possible. These techniques allow exploitation of the advantages inherent to the MR imaging experiment: unsurpassed soft tissue contrast and multiplanar imaging capabilities. Magnetic resonance imaging of the small and large bowel has thus moved from a hypothetical possibility to a practical reality. This manuscript describes some of the underlying fast imaging techniques for display of the small and large bowel. Furthermore, it discusses the plethora of available oral and rectal contrast agents. Finally, clinical indications for MR of the small and large bowel as well as the rectum are described in light of the available literature. Advantages and disadvantages relative to computed tomography and other imaging techniques are discussed.

“…Barium sulfate is inexpensive and has an excellent safety profile [18] Orally as well as rectally administered barium can provide good contrast in MR imaging of the gastrointestinal tract [19,24,25,26,27,28]. The signal intensity can vary depending on the degree of dilution of barium sulfate.…”

“…Barium causes loss of signal in the bowel because it replaces the water protons by barium particles. Barium-containing agents must not be administered in cases of suspected bowel perforation, before bowel surgery and within one week after endoscopic polypectomy (10).…”

Purpose: The purpose was to find an oral contrast agent that can be utilized in MRI of the small bowel and fulfill the following criteria: natural, with no or minimal side effects, nonexpensive, causes the maximum bowel distension and has the best imaging quality with no artifacts. Methods: Fourteen healthy volunteers were included. Each volunteer underwent 3 MRI examinations on different days using 3 different oral contrast materials; water, milk and pineapple juice. Coronal T2WI MRI was done at KAUH Diagnostic Radiology department. Standardized questionnaire was used to study post-MRI abdominal complaint. Statistical analysis was done using SPSS program version 17.0. Results: All tested contrast agents could significantly distend the small bowel loops with the p value <0.05. Pineapple juice could distend up to 5 segments in 7 volunteers. Good image quality was depicted in 50% of volunteers using juice, while water showed the worst results where 75% had bad image quality. The highest percentage of image artifacts was found with milk (64.3%). Conclusion: Pineapple juice has the highest ability of bowel distention and good image quality with insignificant image artifacts and no reported side effects.

“…Oral contrast agents producing high signal intensity (SI) such as paramagnetic agents in oil emulsions (3), or low SI such as super paramagnetic particles (4,5) or barium (9) are being examined for improving the delineation of the pancreas from the gastrointestinal tract. Recently, studies have been concerned with sequences that reduce the incidence of artefacts or improve the dynamic range of intra-abdominal SI (10)(11)(12).…”

The effects of acute pancreatitis on MR imaging signal intensities (SIs) were determined in an experimental study at 1.0 T. Oedematous pancreatitis was induced in 9 piglets and haemorrhagic pancreatitis in II piglets. Each animal served as its own control for MR imaging before and after induction of pancreatitis. TI-weighted spin echo (450/15 ms) and dynamic turbo FLASH (flip angle 8°) sequences were used without contrast medium in testing the stability of the SI measurements. There was no significant difference in the SI-versus-time curves of the pancreas in piglets with oedematous and haemorrhagic pancreatitis. However, the difference in mean SIs between healthy and diseased piglets was significant. Thus, although non-contrast MR may be useful in the diagnosis of acute pancreatitis, it does not distinguish between oedematous and haemorrhagic pancreatitis.
