Magnetic permeability as a predictor of the artefact size caused by orthodontic appliances at 1.5 T magnetic resonance imaging

Conclusions The permeability can be reliably assessed by conventional measurement devices and the artefact size can be predicted. The radiologist is able to decide whether or not the orthodontic attachments should be removed. Clinical relevance This study clarifies whether an orthodontic appliance must be removed before taking an MRI. (Source: Clinical Oral Investigations)
