The diagnostic potential of magnetic resonance fluoroscopy in patients with achalasia

Motivation: A non-invasive imaging method, such as MR fluoroscopy, was used for treating achalasia patients. Goal(s): To determine whether MR fluoroscopy can diagnose patients with achalasia. Approach: We included 39 achalasia patients and 39 healthy volunteers. MR fluoroscopy was performed to observe the structure of the gastroesophageal junction. Results: We measured his angle, the esophageal width, the width of esophageal hiatus, the sphincter length, the angle between the lower esophagus and the longitudinal axis, and the angle between the lower esophageal sphincter and horizontal axis. The parameters of the patient group were statistically and significantly different from those of control group. Impact: MR fluoroscopy can be effectively used in the clinical diagnosis of cardiac achalasia. The MR imaging method is a non-radiological tool and is used to evaluate anatomical structures.
