Diffusion-tensor MR imaging at 1.5 and 3.0 T: initial observations

Radiology. 2001 Nov;221(2):550-6. doi: 10.1148/radiol.2212001823.


Diffusion-tensor MR imaging was compared at 1.5 and 3.0 T. With sufficient signal-to-noise ratio, we found no differences in fractional anisotropy. With a 40% higher signal-to-noise ratio at 3.0 T, higher resolution could be obtained without introduction of noise-related errors, albeit at the cost of increased geometric distortions caused by 3.0-T magnetic field inhomogeneities.
