MRI's can have both positive and negative effects. It clearly has a role, however it should be the role of health care professionals to use them wisely.
As mentioned in the video, in the graph below Brinjiki et al showed a high prevalence of MRI imaging identifying various pathology's in 3110 people ''without any pain'' with ages from 20 to 80 years old. In a similar study Nakashima et al showed similar results in over 1200 neck MRIs in subjects again with NO pain.
