Ajaj et al. evaluated whether patients with increased or decreased gastric motility can be differentiated from healthy volunteers by means of real-time MRI [9]. In this study, ten healthy volunteers, ten patients with gastroparesis and ten patients with functional pylorospasm/peptic pyloric stenosis underwent real-time MRI. All patients were examined on two separate days: once prior to therapy and once after adequate therapy. Antral motility was quantified by calculating the gastric motility index. Patients with gastroparesis showed a lower motility index compared with the healthy volunteer group, while the mean motility index of the patient group with pylorospasm was more than three times higher than that of the reference value of the volunteer group. However, the gastric motility index in the patient group with gastroparesis increased, and in the group with functional pylorospasm/peptic pyloric stenosis, it decreased significantly after therapy. This study shows that MRI can clinically assess patients with suspected gastric pathophysiology as it is able to differentiate healthy subjects from patients with gastroparesis.
