MRI – Magnetic Resonance Imaging
MRI is a non-invasive imaging tool used to aid in diagnosis, staging of progression of illness and treatment planning. It uses a powerful magnetic field and radiofrequency waves rather than radiation to see the structure and function of organs in the body. Images have superior soft-tissue contrast and can differentiate between tissues, bones, muscles, spinal cord, etc.
