Comparative Analysis of Barium Follow Through with CT Enterography and Magnetic Resonance Enterography in Radiological Diagnostics: A narrative review of literature

Abstract

Background: Radiological imaging is fundamental in diagnosing gastrointestinal (GI) disorders, with Barium Follow Through (BFT) and Magnetic Resonance Enterography (MRE) being prominent modalities. While BFT employs barium sulfate and X-ray imaging, MRE utilizes MRI technology, offering superior soft tissue contrast and multiplanar imaging without radiation.

Objective: This narrative review aims to compare BFT and MRE in GI diagnostics, emphasizing their technical methodologies, diagnostic efficacy, patient safety, economic implications, and clinical applications.

Methods: A literature search was conducted across reputable databases using specified keywords. Studies comparing BFT and MRE in GI diagnostics were analyzed for a comprehensive understanding of their comparative strengths and limitations.

Results: MRE demonstrated higher sensitivity and specificity, particularly in detecting inflammatory bowel disease and small bowel tumors, while BFT remained valuable for assessing structural abnormalities despite challenges in detecting subtle mucosal abnormalities. Patient safety considerations favored MRE due to its radiation-free nature, though contraindications such as claustrophobia existed. Economically, while BFT was initially perceived as more cost-effective, MRE's higher reimbursement rates and diagnostic accuracy offered long-term benefits.

Conclusion: This review provides valuable insights into the comparative strengths and limitations of BFT and MRE, facilitating informed decision-making and optimizing imaging strategies in clinical practice. Interdisciplinary collaboration is essential for improving diagnostic accuracy and patient outcomes in GI disorders.
