How does MRI operate?
MRI images are formed when signals emitted by body tissue are processed by software and turned into clinical images. These signals are generated using a safe magnetic field in combination with radio waves of a specific frequency. Different tissue characteristics are translated into different contrast levels on the image. A typical procedure averages 30 minutes or longer, depending on the type of information required by your physician. You can help to make your images as clean as possible by relaxing and remaining still during the exam.
