Application of MRI for small intestinal diseases
1Department of Radiology, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Korea.
Abstract:
Until recently, MRI has not been considered to be suitable for the evaluation of the small intestine due to artifacts associated with bowel peristalsis or respiration. However, recent advances of MR techniques enable the acquisition of clear images of the small intestine. Therefore, the purpose of this article is to review the details for the application of MRI in patients with small intestinal diseases. This article discusses bowel preparation and oral contrast agents as well as MR techniques and pulse sequences. Thereafter, the usefulness of MRI for the lesions in the peritoneal cavity or in the gastrointestinal tract are discussed. Small intestinal lesions are categorized into inflammatory, neoplastic, ischemic, and obstructive bowel diseases. In conclusion, MRI can be used as an alternate modality of choice for imaging various diseases of the small intestine.
Insights
Magnetic resonance imaging (MRI) is now a viable option for evaluating small intestinal diseases. Recent advancements allow clear imaging, making MRI a valuable diagnostic tool for various conditions.
Area of Science:
- Radiology
- Gastroenterology
- Medical Imaging
Background:
- Historically, magnetic resonance imaging (MRI) faced challenges in small intestine evaluation due to motion artifacts.
- Recent technological progress in MRI techniques has overcome these limitations, enabling high-quality imaging.
Purpose of the Study:
- To review the application of MRI for diagnosing small intestinal diseases.
- To detail essential considerations for effective small bowel MRI.
Main Methods:
- Discussion of optimal bowel preparation strategies.
- Review of suitable oral contrast agents for small intestine visualization.
- Explanation of relevant MRI techniques and pulse sequences.
Main Results:
- MRI demonstrates significant utility in identifying lesions within the peritoneal cavity and gastrointestinal tract.
- The modality effectively categorizes small intestinal diseases, including inflammatory, neoplastic, ischemic, and obstructive conditions.
Conclusions:
- Magnetic resonance imaging is a suitable and effective alternative for imaging diverse small intestinal pathologies.
- MRI offers a comprehensive approach to diagnosing a wide spectrum of small bowel diseases.
