Magnetic Resonance Imaging (MRI) & Angiography (MRA)
Magnetic resonance imaging (MRI) is a valuable diagnostic tool that provides a noninvasive way for your doctors to see the internal structures of your body using radio waves inside a magnetic field. MRIs are particularly useful for viewing conditions involving soft tissue that might be obscured by bone in other types of diagnostic imaging.
Our Health Information Library offers in-depth information on magnetic resonance imaging of different areas of the body, including why they’re done, how to prepare, what to expect and what the test results will show. A general overview is available under Magnetic Resonance Imaging (MRI), with specific tests covered in the following sections:
Magnetic resonance imaging (MRI) of the abdomen
Magnetic resonance imaging (MRI) of the breast
Magnetic resonance imaging (MRI) of the head
Magnetic resonance imaging (MRI) of the knee
Magnetic resonance imaging (MRI) of the shoulder
Magnetic resonance imaging (MRI) of the spine
An MRA uses MRI technology to provide your doctor with images of blood vessels inside your body. If your doctor refers you for computed tomography angiography (CTA), we encourage you to read the comprehensive explanation of a magnetic resonance angiogram (MRA) to learn more about the procedure and what to expect.
Talk to Your Doctor
We hope this information helps you gain a better understanding of MRI scanning and encourage you to talk to your doctor about any questions or concerns you have about your MRI or MRA scan.
