Finally, high cost of the MRI, limited availability, long acquisition times, and the need for greater patient cooperation compared with CT and ultrasound currently prevent its widespread use as the primary imaging modality for suspected acute appendicitis. For example, a prospective randomized pediatric cohort study comparing rapid MRI to ultrasound demonstrated ED length of stay on average to be 100 min longer in the MRI group compared with the ultrasound group [44]. Furthermore, MRI was associated with ED charges on average $4887 higher compared with ultrasound [44]. The authors concluded that in the diagnosis of appendicitis in young patients, ultrasound-first imaging is more time-efficient and less costly than rapid MRI despite inconclusive examinations with US [44]. The authors further speculated that ultrasound should be the first-line imaging modality for acute appendicitis unless the process of obtaining a rapid MRI becomes more efficient and less expensive [44].
