Objective: To utilize the effectiveness of MR-Enterography as a potential investigating marker for the diagnosis of Crohn’s disease. Conclusion: This article reviews the technique of performing MR enterography which aids in the diagnosis of Crohn’s disease, it also serves accurate information about the severity of the disease and complications of it that may guide for the surgical or medical treatment.

DOI10.14302/issn.2572-3030.jcgb-13-366 Magnetic resonance enterography(MRE) is a new promising technique that may combine both the cross-sectional imaging, conventional enterography and enteroclysis1, 2, 3. MRE has become preferred approach for the diagnosis of inflammatory bowel diseases, tumors, malabsorbtion etc because of its high soft-tissue contrast resolution and multi-planar imaging capability1, 3, 4. Lack of radiation exposure and superposition of bowel loops, its use in pregnancy and in patients with iodine allergy are the other advantages of MRE2, 5. The other MRI based techniques are the routine dynamic abdominal MRI and MR Enteroclysis which present the disadvantages of high costs, motion artefacts and long scanning time, motion artefacts can be eliminated by some fast imaging sequences2, 4, 5, 6 MR Enteroclysis has the disadvantage of nasojejunal intubation which is performed under flouroscopy and exposure to ionizing radiation, MRE eliminates this disadvantage with the administration of oral contrast agent3, 5, 6, 7.A few limitations for MRE are reported up to now, those are: Patients intolerance for drinking the Oral contrast agents(OCA), nausea and vomit of the patients, patients dyscomfort in the magnet and claustrophobia, general contraindications against MR imaging and magnetic field due to inappropriate instruments of the patients against the magnet like metalic prosthesis and implants, cardiac pacemakers, metalic sutures,etc. Adequate small bowel distention is vital for an optimal enterographic examination as collapsed or contracted small bowel loops may mimic some pathologies, mask some intraluminal lesions or may cause overdiagnosis with exaggerating of wall thickness3,6, 7, 8. OCA has been administered to ensure the optimal bowel distention, they are
