MR enterography is option for pediatric patients with Crohn disease

Parents with children nine years old and older who have Crohn disease should ask their children's doctor about MR enterography as a replacement for small bowel x-rays or CT enterography, a new study indicates.

Children with must often undergo repeated examinations, which, with x-rays and CT, could lead to significant , said William A. Faubion, Jr., MD, one of the authors of the study.

"MR enterography does not require any radiation, however the patient does have to drink an oral contrast agent, must hold their breath at times and must limit their motion during the examination, all which can be difficult for ," said Dr. Faubion.

The study—the largest North American study of its kind-- analyzed 70 pediatric patients who underwent MR enterography to review the quality of MR enterography images and to determine if pediatric patients could tolerate the examination. The study, conducted at Mayo Clinic College of Medicine in Rochester, MN, found that "MR enterography performs as well in children as it does in adults. MR enterography could accurately identify inflammation 80% of the time in the terminal ileum, 79% of the time in the right colon and 90% of the time in the left colon," said Dr. Faubion. While a similar study using CT in children has not been performed, in adults MR and CT enterography have been found to be equivalent methods of imaging, said Dr. Faubion.

"In addition, we found that MR enterography could be successfully completed in the majority of children nine years old and older, without having to sedate them," Dr. Faubion said. The number of patients who suffered side effects was low; two patients experienced nausea and one patient fainted, however, no ongoing care was required, he said. One patient refused to drink the contrast material. Tolerance to the procedure was related to the amount of contrast the patient had to drink; the study found that younger could drink a smaller amount of contrast material without negatively affecting the MR enterography image quality, Dr. Faubion said.

The study appears in the September issue of the American Journal of Roentgenology.
