Advanced MRI Scanners May Be Just as Effective Without Dye, Says New Study

March 18, 2019

Researchers from Germany report that using powerful 3 Tesla MRI without a contrast dye to assess disease activity in 359 people with MS was just as effective for identifying new lesions (damaged areas) as brain scans using the dye.  Currently, many scanners are 1.5 Tesla, which is less powerful. (Tesla is the unit of measurement that indicates the strength of a magnetic field.) As 3 Tesla machines become more widely available, these results may help to reduce the need for contrast dyes like gadolinium, the use of which has recently raised some concern.

About Multiple Sclerosis

Multiple sclerosis is an unpredictable, often disabling disease of the central nervous system that disrupts the flow of information within the brain, and between the brain and body. Symptoms range from numbness and tingling to blindness and paralysis. The progress, severity and specific symptoms of MS in any one person cannot yet be predicted, but advances in research and treatment are leading to better understanding and moving us closer to a world free of MS. Most people with MS are diagnosed between the ages of 20 and 50, with at least two to three times more women than men being diagnosed with the disease. MS affects more than 2.3 million people worldwide.
