Data suggest that MRI (Magnetic Resonance Imaging) at a level of 1.5 Tesla units or (15,000 Gauss) is acceptable in women using Paragard. CooperSurgical (the manufacturer of Paragard) has not conducted any studies to evaluate the safety of MRIs in women using Paragard. Please speak to your healthcare provider to determine if you may have an MRI performed with Paragard in place.
