What Is An MRI?
Magnetic resonance imaging (MRI) is a noninvasive medical procedure used to produce detailed pictures of organs, soft tissues, bone and virtually all other internal body structures. Magnetic resonance imaging does not use ionizing radiation. Under controlled circumstances, magnetic field and radio frequency energy are used to create computer images. These images are interpreted by SJRA specialists trained in sub specialties such as neuroradiology, orthopedic radiology, cardiothoracic radiology, and much more. Feel free to view all of our SJRA sub specialists and physicians.
What Are The Different Types of MRIs?
There are three main types of MRIs. The first type is a MR Angiography. An MR Angiography is a noninvasive medical procedure that uses a magnetic field and radio frequency energy to evaluate blood vessels and help identify abnormalities or plaque. This exam does not requires the use of any form of radiation, but may require the use of contrast material to better highlight the area being scanned.
The second type is a MR Arthrogram. Similar to a MR Angiography, An MR Arthrogram is a noninvasive medical procedure that uses a magnetic field and radio frequency energy to evaluate joints. This type of MRI is incredibly useful for orthopedics and pain specialists to identify why a particular joint is causing discomfort for a patient.
Lastly, the final type of MRI is a Magnetic Resonance Venography (MRV). An MRV utilizes the same kind of technology as other MRI types, but focuses on producing high quality images of your veins. This type is very useful to identify various blood clots, strokes, and much more.
How Do I Prepare For An MRI?
It is important to pay close attention to all guidelines your referring physician and our SJRA staff provides. These guidelines provide details on what food and drinks you can have prior to your appointment. In most cases, MRIs require some form of fasting.
Avoid wearing uncomfortable clothing and any article that contains metal such as zippers, jewelry, buttons, and so forth. If you have any metal implants in your body such as hearing aids, joint reconstruction, or dentures, please inform our SJRA technologist prior to starting the MRI scan.
