Static & Gradient Fields Q&A's
- Which types of metal are the most dangerous around a magnetic field?
- If steels and permanent magnets are potentially dangerous, which metals are "safe" around the MRI field?
- Is the MRI field strong enough to magnetize a piece of metal?
- I don't understand how an object's shape affects its magnetization.
- How do you calculate the magnetic force pulling a piece of metal toward the scanner?
- So then, exactly where is the most dangerous place for force or torque near an MRI scanner?
- How are translational force and torque measured for an implant?
- Do the strong static magnetic fields used in MRI pose any health risks?
- What causes some patients to experience dizziness and/or vertigo in an MR scanner?
- What causes the flickering lights observed by some MRI patients?
- Some patients undergoing MRI report a metallic taste. Is that due to an effect on dental fillings?
