Double- strand breaks in lymphocyte DNA of humans exposed to [ 18 F]fluorodeoxyglucose and the static magnetic field in PET/MRI
Authors not listed · 2020
3-Tesla static magnetic fields in PET/MRI scans don't cause DNA damage or worsen radioactive tracer effects.
Plain English Summary
Researchers tested whether the 3-Tesla static magnetic field used in PET/MRI scans might increase DNA damage when combined with radioactive glucose injection. They found the radioactive tracer caused a 28% increase in DNA breaks in immune cells, but the magnetic field alone caused no damage and didn't worsen the radioactive effects.
Why This Matters
This study addresses an important safety question as PET/MRI becomes more common in medical imaging. The good news is that the powerful 3-Tesla static magnetic field doesn't appear to amplify DNA damage from the radioactive tracer used in these scans. However, this research highlights a broader principle we should remember: medical devices often expose us to multiple forms of electromagnetic energy simultaneously, and we need studies like this to understand potential interactions.
What's particularly relevant is that 3-Tesla is an extraordinarily strong magnetic field - about 60,000 times stronger than Earth's magnetic field. If static magnetic fields at this intensity don't cause measurable DNA damage in a controlled laboratory setting, it provides some reassurance about the static magnetic fields we encounter in daily life, which are orders of magnitude weaker. The study demonstrates the importance of rigorous testing when new medical technologies combine different types of electromagnetic exposures.
