Image artifacts on prostate diffusion-weighted magnetic resonance imaging: Trade-offs at 1.5 tesla and 3.0 tesla
Diffusion Magnetic Resonance Imaging
Image Interpretation, Computer-Assisted
At 3.0 T (as compared to 1.5 T), increased SNR on prostate DW-MRI comes at the expense of geometric distortion and can also lead to more pronounced ghosting artifacts. Therefore, to take full advantage of the benefits of 3.0 T, further improvements in acquisition techniques are needed to address DW-MRI artifacts corresponding to higher field strengths.
