MRI of inflammatory bowel disease by ProQuest


Overall, the terminal ileum and proximal colon are the parts of the intestine that are most often affected in patients with IBD.1 Numerous techniques are used clinically to assess IBD, including ileocolonoscopy, ultrasound, capsule endoscopy, and/or surgical techniques in conjunction with tissue biopsy.2-4 However, these techniques are either invasive (endoscopy), associated with low diagnostic accuracy (ultrasound), or are contraindicated in a considerable number of cases (capsule endoscopy). Another rationale favoring the use of MRI to assess IBD is the greater safety of intravenous (IV) contrast for MR relative to CT contrast agents, since MR contrast agents are associated with far fewer anaphylactic reactions and are less nephrotoxic.10 MRI of inflammatory bowel disease Bowel distension An appropriate degree of bowel distension is a prerequisite for adequate MRI studies of IBD.
