“…Last, 20 patients were given the oral contrast agent through a fluoroscopically placed nasojejunal tube during sedation. Although no major adverse events occurred in the present study, and Sadigh et al (31,32) reported that fluid instillation via nasojejunal intubation with a patient under general anesthesia is a safe technique, the risk of aspiration cannot be ignored. Accordingly, further research is needed to determine whether conventional abdominal MRI is a safer alternative for the diagnosis of MD in younger children.…”

Background: The aim of this study was to explore the magnetic resonance enterography (MRE) imaging manifestations of a symptomatic Meckel's diverticulum (MD) in pediatric patients in order to provide a reference for the diagnosis of the condition. Methods:The medical records of 31 pediatric patients with MD from May 2014 to October 2020 were retrospectively analyzed. The inclusion criteria were patients with MD accompanied by unexplained gastrointestinal bleeding, anemia (except hematological diseases), chronic persistent abdominal pain, repeated intussusception, or intussusception in older pediatric patients during surgery. The clinical variables (age, sex, and hemoglobin) and imaging, surgical, and pathological findings were recorded.Results: MD was definitively identified in 28 patients, with the following characteristics: a blind-ending fluid-filled and/or gas-filled structure (n=23), an elongated shape (n=1), a dumbbell shape (n=1), and a solid mass (n=3). The diverticula were located in the right lower quadrant (n=16), the right abdomen at the level of the umbilicus (n=3), the right upper quadrant (n=2), the left upper quadrant (n=2), and the midline lower abdomen (n=5). Supply arteries were visualized in nine cases. In all cases, mural enhancement was comparable to that of the adjacent small-bowel (SB). Extravasation of the intravascular contrast medium was seen in two cases. Peripheral structural abnormalities included mesenteric fat stranding (n=7), hemorrhage in the adjacent lumen (n=3), free intraperitoneal gas (n=1), abnormal fluid retention (n=2), intestinal obstruction (n=1), and lymph node enlargement (n=7). A normal appendix was identified in 18 cases.Conclusions: MRE is an appropriate method of diagnosing symptomatic MD in pediatric patients and is particularly useful in the assessment of complications.

“…The procedure may be performed in an awake state as in a cooperative older child or using general anesthesia(GA) in younger children. Mollard et al showed that in children less than 10 years of age, >90% of MR enterographic examinations were performed under GA. (4) However, this constituted only 20% of the total pediatric MR enterographic examinations performed in their high volume center. (5) Limiting the motion artifacts and breath holding is required to allow certain sequences which are necessary for interpreting the study.…”

“…The type of contrast agent and the optimal volume that does not cause adverse effects remain undetermined. For children, 600-1,000 mL volume depending on age [ 19 ] or 20 mL per kilogram of body weight (maximal dose, 1,350 mL) is generally considered optimal [ 19 20 21 22 23 24 ]. Ingestion of the contrast material over regular intervals facilitates consistent bowel distension.…”

Crohn's disease is a chronic idiopathic inflammatory disease of the intestines characterized by frequent relapse and remission. It often develops in children and adolescents, who are vulnerable to repeated exposure to ionizing radiations. Magnetic resonance enterography (MRE) is an increasingly important radiation-free imaging modality that is used to evaluate pediatric patients with Crohn's disease. MRE can evaluate extraluminal and extraintestinal abnormalities as well as the status of the bowel wall. In addition, MRE has an advantage in the evaluation of the small bowel involvement. MRE can be used for the initial diagnosis of Crohn's disease, and can aid in the assessment of disease activity and complications such as penetrating and fibrostenotic diseases. The aims of this article are to review the MRE technique for obtaining diagnostic and high-quality images and to discuss interpretations of imaging findings in patients with Crohn's disease.

MR enterography under the age of 10 years: a single institutional experience

Abstract: Diagnostic-quality MRE can be performed successfully in young children. The majority of MRE exams were performed under GA, with only occasional minor side effects/adverse events.
