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. Symptoms range from numbness and tingling to blindness and paralysis, and there is currently no cure for MS. 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. An estimated 1 million people live with MS in the United States. Most people with MS are diagnosed between the ages of 20 and 50, and it affects women three times more than men.
