Do MRIS damage DNA?

We conclude that while a few studies raise the possibility that MRI exams can damage a patient's DNA, they are not sufficient to establish such effects, let alone any health risk to patients… We consider that genotoxic effects of MRI are highly unlikely.

Can MRI destroy body cells?

MRI is thought to have no long-term side effects, conversely to ionizing radiation-based imaging techniques (x-ray angiography, coronary computed tomographic angiography, and nuclear imaging), which can induce cell death or persistent DNA damage, resulting in mutagenesis, carcinogenesis, and genomic instability.
