Magnetic Resonance Imaging (MRI) FAQs

What is a Magnetic Resonance Imaging (MRI) exam?

MRI San Francisco | Marin County CAMagnetic Resonance Imaging (MRI) is a method of advanced imaging that allows doctors to look at soft tissues such as muscles and nerves in fine detail. An MRI does not replace standard X-rays, and in many instances X-ray adds significantly to the value of an MRI.

Why would I need an MRI exam?

An MRI is especially useful for the diagnosis of soft tissue injuries such as ligament tears, meniscal tears, cartilage damage, rotator cuff problems, disc herniations, and spine disorders.

How does an MRI work?

An MRI uses a large magnetic coil that takes pictures using radio waves and magnetic fields instead of X-rays. Depending on the body part imaged, the test takes about thirty minutes and does require a portion of the body to be placed inside the scanner; i.e. a closed MRI. A closed MRI provides a much higher quality image than an open MRI, and many doctors, particularly for the spine, specifically request that patients do not get an open MRI. The test does not require sedation, is non-invasive, and there is no pain.
