Glossary: Magnetic Resonance Imaging
 


Definition
A technique used in diagnosis that combines radio waves and magnetic forces to produce detailed images of the internal structures of the body.

Also: MRI

Topics Related To Magnetic Resonance Imaging
AdenomyosisThe Condition
"...Diagnostic tools include an abdominal X-ray that is taken after ingestion of contrast (a dyelike material that is visible on X-ray); MRI with contrast medium that can often distinguish adenomyosis from fibroids (although its cost precludes its routine use); and a transvaginal ultrasound, which can provide an accurate diagnosis but,..."

The Condition
"...Brain aneurysms can be detected by imaging tests such as magnetic resonance imaging (MRI), computed axial tomography (CAT scans) and angiograms..."

Brain Tumor

The Condition
"...It is sometimes hard to know whether a CT Scan or MRI should be done if someone exhibits some of the symptoms and signs of brain cancer, but it is important to know that these studies will usually definitively establish whether a brain tumor is..."

Post-Polio Syndrome

The Condition
"...In addition to the neurological examination, doctors often recommend tests, such as imaging studies (computerized tomography and magnetic resonance imaging), to rule out other disorders with similar symptoms..."
