Anywhere in the body may undergo extensive changes and be at risk of developing a tumor. Magnetic resonance imaging can be performed on the liver, bile, pancreas, spleen, uterus, ovary, and prostate and can reveal many problems in the body.Because radio waves are used in magnetic resonance imaging, the side effects of MRI are usually not significant. However, sometimes contrast dye can cause side effects such as skin rashes, headaches, and dizziness.For the following groups, this type of imaging is not prescribed and is dangerous:Normal imaging in pregnant women (in the first trimester) and the use of contrast material during pregnancy is prohibited; People who have had an allergic reaction to contrast material in the past; People who have any kind of metal in their body. In order to be able to examine how MRI is performed, we simultaneously examine care in three time periods, before, during, and after MRI: If you have a question about what to eat before MRI, pay attention to the fact that you should be completely fasting for about 4 hours before the imaging (the meaning of ''Unknown'' is that you should even refrain from drinking water, smoking, and chewing Avoid chewing gum too). In some cases, you may be asked not to eat or drink anything for 4 hours before the scan. Sometimes you may be asked to drink a lot of water before the scan, depending on the opinion of the doctor and imaging technician. You will usually be asked to stop taking medications in consultation with your doctor.
