Purpose:
To investigate whether a combined examination with MRI enteroclysis and MRI colonography is practicable and would provide additional findings in the regions seen with ileo-colonoscopy in the work-up of patients with Crohn's disease.
Material And Methods:
Twenty-five consecutive patients with Crohn's disease (CD) (age range 19 to 42 years, mean age 29.2 years, gender ratio male:female 8:17) were retrospectively studied. All patients underwent conventional ileo-colonoscopy as a standard of reference followed by a combined examination of MRI enteroclysis and MRI colonography at 1.5T within 15 days. Two blinded radiologists evaluated the MRI examinations and compared them with the colonoscopic results.
Results:
The MRI examination detected 31 inflamed bowel segments in 25 patients. In comparison to colonoscopy, 5 additional, endoscopically inaccessible lesions were found by MRI and only 2 lesions were missed by MRI. Compared to colonoscopy, MRI found 7 of 10 fistulas detected by colonoscopy, and 3 otherwise indiscernible abscesses. The detection of inflamed bowel segments by means of MRI (endoscopy) revealed a sensitivity of 88.8 % (100 %), specificity of 80 % (100 %) and an overall accuracy of 96 % (100 %).
Conclusion:
This study provides strong evidence that the combination of MRI enteroclysis and MRI colonography is practicable and supplies additional results regarding the regions which are not seen with ileo-colonoscopy in the work-up of patients with Crohn's disease.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
