Magnetic Resonance Imaging (MRI) is a test that uses a magnetic field and radio waves to create detailed images of the body’s organs and tissues. An MRI gives your doctor a different view of the structures in the body by pinpointing problems that cannot be seen using other imaging methods.
An MRI machine is a large tube shaped structure with an exam table. The part of the body that the MRI is requested for will be guided into the tube. During the exam the magnetic field will temporarily realign hydrogen atoms in your body. Radio waves then cause these aligned atoms to produce very faint signals, which are used to create cross-sectional MRI images or 3D images that may be viewed from different angles.
MRI’s are requested by your doctor when they want to examine your organs, tissues, and skeletal system. MRI’s can be used for:
