Flavonoids are responsible for pigments in many fruits and vegetables. Studies have shown that they may help reduce the risk of Parkinson's disease, cardiovascular disease and stroke. A particularly valuable flavonoid in onions is quercetin, which acts as an antioxidant that may be linked to preventing cancer. âIt also might have heart health benefits, though more studies need to be done,â said Angela Lemond, a Plano, Texas-based registered dietitian nutritionist and spokesperson for the Academy of Nutrition and Dietetics.
Magnetic resonance imaging (MRI) is very safe and most people can have the procedure, including pregnant women and babies. However, there are some instances where an MRI scan may not be recommended, because the strong magnets used during the scan can affect any metal implants or fragments in your body. Before having an MRI scan, you should tell medical staff if: you think you have any metal in your body. you're pregnant or breastfeeding.

Best Answer: The major issue with MRI is metal in the body, but you aren't allowed near the magnet if there is any risk of that metal causing damage if you are put in the magnet, so that's not really a side effect. There are a number of well known minor possible side effects.RI works using radiowaves not microwaves, but it can still heat the body slightly. Not enough to do any harm, but a few patients can find it uncomfortable. Also there is a slight possibility that the MRI magnet can cause temporary dizziness, but that last minutes. Long term there appears to be no side effects.
