Effects of Gd bolus on DTI measurements in Skeletal Muscle

Bells S, Noseworthy M

Diffusion tensor imaging is now a commonly used MR procedure. However, it is done either before or after Gd contrast enhanced scans without sound knowledge of the agents effect on tensor measurements. In this study we show that Gd contrast affects calculated diffusion tensor parameters, thus suggesting DTI should be performed prior to contrast enhanced scans.
