Inflammatory bowel disease (IBD) is a debilitating, chronic, inflammatory disease comprising two predominant pathologies: Ulcerative colitis (UC) and Crohns disease (CD). But all these methods of examination of the intestine are accompanied by almost the same unpleasant sensations. The most commonly used agents include osmotic agents such as 2.5% mannitol, methylcellulose, or polyethylene glycol, which promote luminal distention by slowing down water absorption in the jejunum. MR colonography with barium-based fecal tagging: initial clinical experience. MRE-based disease scores have recently been developed to quantify disease activity in Crohns disease. MR technology is better at imaging soft tissue (such as fistulas), and it does not use ionizing radiation. Capsule endoscopy (CE) can allow visualization of the mucosa throughout the small bowel; however, it does not allow tissue sampling and is contraindicated in stenosis or obstruction. and transmitted securely.
