Esophageal MRI is emerging alternative to endoscopic ultrasound (EUS) and computed tomography (CT) for the detection and staging of cancer. Esophageal MRI has great potential for screening, active surveillance post-neodjuvant therapy and ruling out surgery for patients with higher stage cancer. The major challenges in esophageal imaging are the spatial resolution, as the esophageal wall is only approximately 3mm thick, and cardiac related motion artifacts. This prospective study aimed to address these challenges by developing a protocol for high-resolution T2-weighted and motion-robust diffusion-weighted imaging of the esophagus and periesophageal tissue.
