This study aimed to summarize a new technology for magnetic resonance imaging (MRI) of swallowing in the evaluation of esophageal function and gastroesophageal reflux disease (GERD) as well as for postoperative imaging after antireflux surgery. A search was carried out in the Medline database to identify relevant publications. Magnetic resonance swallowing is a new, simple, nonionizing radiological method used to confirm the diagnosis of GERD or any motility disorder. The MR diagnosis of GERD was concordant with the pH-metry in 82% of patients. However, the main clinical indication is for evaluation of the cause of fundoplication failure in the postoperative patient who suffers new or recurrent symptoms. Magnetic resonance swallowing is the only method that enables a direct view of the wrap itself. In up to 93% of cases, the correct position of the fundoplication wrap could be determined; 67% of malpositions were assessed, as well as all cases of wrap. Real-time MRI swallowing, as a noninvasive and nonionizing method, offers a new perspective for the combined anatomic and functional visualization of GERD, with the possibility of direct visualization of the surrounding structures.
