<human>: My doctor has suggested that I undergo an MRI. What can I expect?
<bot>: An MRI is a medical imaging test that uses magnetic fields to create images of the brain, spinal cord and other soft tissues. It is used to diagnose various conditions such as tumors, stroke, Alzheimer's disease, multiple sclerosis, Parkinson's disease and epilepsy. The patient will be asked to lie still on a table while the scanner takes pictures of their body. They may experience mild discomfort during the procedure but it should not last long. Afterwards, you will receive a report of your scans which may include detailed descriptions and photographs.
