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 disease of the central nervous system. Currently there is no cure. Symptoms vary from person to person and may include disabling fatigue, mobility challenges, cognitive changes, and vision issues. An estimated 1 million people live with MS in the United States. Early diagnosis and treatment are critical to minimize disability. Significant progress is being made to achieve a world free of MS.
