Sorry to hear about
the issues your daughter has been suffering from.
An MRI has the capability to detect pathologic bowel segments with high sensitivity and specificity. This technique plays an important role in diagnosing complications such as fistulas, abscesses and accurately assess inflammatory bowel changes. Along with the lack of ionizing radiation.
Here's information I found in regards to the use of an MRI and Crohn's disease.
"The use of magnetic resonance imaging for Crohn's disease sufferers has now been quite well established, both in research and literature. A specific, non-invasive imaging technique, called MR Enterography, yields high contrast images of intestinal inflammation, abscesses and fistulas in the small bowel. It utilizes dynamic image acquisition following the administration of intravenous contrast to provide information about
the time course of bowel wall enhancement. This serial imaging of bowel wall enhancement over time may help to distinguish active disease from inactive disease. Such dynamic imaging is not routinely performed with CT (computed tomography) because of the radiation exposure associated with serial image acquisition. As a result, MR enterography has been shown to be superior to CT for differentiating between acute and chronic inflammation in areas of the diseased bowel, which is critical for deciding on medical vs. surgical treatment. Recent studies comparing CT enterography and MR enterography have demonstrated that both techniques are excellent at detecting features associated with Crohn’s disease and that the differences in sensitivity and specificity between the two techniques were not statistically significant."
A Colonoscopy and getting a biopsy would be ideal. These are the tests that should be performed-
A physical examination by a GI, checking for tenderness or any inflammatory masses present at the lower right quadrant of the abdomen.
Also the GI should do a complete blood count test. This is to possibly reveal if Crohn's is present, Anemia, White blood cell levels, Differential, Platelet count and an ESR (Erythrocyte sedimentation rate). Also Stool tests. Then further testing to be included, Radiologic and Endoscopic Testing. Such as a CT, Ultrasound, MRI and Endoscopy.
I'm glad that you pursued getting an MRI and have been proactive to help your daughter get the tests done.
I hope this helps and wish you daughter all the best.
