“…Two mathematically established methods, Lomb-Scargle and Sinus-Fitting were reliable in the automated assessment of small bowel contraction frequency 32 . One optimized technique based on registration methods showed excellent agreement between observers for the analysis of overall gut motility in unprepared small bowel conditions 37 .…”

Technical guidelines for magnetic resonance imaging (MRI) of the small bowel (SB) in the setting of inflammatory bowel diseases (IBDs) were detailed in a 2017 consensus issued by European Society of Gastrointestinal and Abdominal Radiology (ESGAR) and European Society of Pediatric Radiology (ESPR); however, MRI for non-IBD conditions was not addressed. Hence, we performed a systematic review collecting researches on SB MRI for non-IBDs. The literatures were then divided into morphologic group and functional group. Information about the MRI techniques, gastrointestinal preparation, and details of cine-MRI protocols was extracted. We found that a 1.5 T MRI system, prone positioning, and MR enterography were frequently utilized in clinical practice. Gadolinium contrast sequences were routinely implemented, while diffusion-weighted imaging (DWI) was much less performed. The gastrointestinal preparation varied throughout the studies. No uniform protocols for cine imaging could be established. SB MRI examinations for non-IBDs are far from standardized, especially for functional studies. Recommendations for standard parameters in cine-MRI sequences are difficult to make due to lack of evidentiary support. MRI investigations in non-IBD conditions are needed and the standardization of non-IBD imaging in clinical practice is required.

“…[7] In addition, cine MRI, which has been used for cardiac functional assessment with a high-temporal resolution, was gradually applied for the evaluation for bowel motility without radiation exposure. [8] Accordingly, we conducted the evaluation by using cine MRI for the patient and could precisely assess the patient's entire intestinal peristalsis, and the efficacy of multidrug therapy by using 3T cine MRI result in the patient can be managed conservatively without any surgical interventions.…”

Rationale: Chronic intestinal pseudo-obstruction (CIPO) and pneumatosis cystoides intestinalis (PCI) are rare abdominal diseases and the pathological mechanisms have not been fully elucidated. Systemic sclerosis (SSc), which is characterized by the progressive sclerotic changes of skin and internal organs, is a refractory collagen disease and is frequently associated with digestive disorders including CIPO. Patient concerns: A 68-year-old woman who has been well managed for SSc over the long term, who presented with abdominal fullness for the first time. Diagnoses: Abdominal X-ray and computed tomography (CT) images showed PCI with pneumoperitoneum findings. Based on the diagnosis of CIPO, we evaluated the intestinal peristalsis of the patient by using cine magnetic resonance imaging (MRI). Interventions: Oral medications of 15 g/d of Daikenchuto, 750 mg/d of Metronidazole and Sodium Picosulfate were started for improving the bowel peristaltic movement and decreasing intestinal gas production. Outcomes: A great improvement of CIPO and PCI by multidrug therapy without any surgical treatments for such an unusual case. Lessons: This case indicates that SSc can be accompanied with not only CIPO but also PCI as digestive disorders and that cine MRI, which is a definitely beneficial imaging modality, can intelligibly visualize the peristalsis of the intestines and lead to successful medical control by noninvasive treatment.

Cine MRI assessment of motility in the unprepared small bowel in the fasting and fed state: Beyond the breath‐hold

Abstract: This optimized technique showed excellent inter and intra observer agreement. It was sensitive to changes in motility induced feeding. This technique will be useful to study contractile activity and regional patterns along the gastrointestinal tract under physiological conditions.
