First Clinical Experiences with Simultaneous Multi-Slice Accelerated Diffusion-Weighted Imaging Throughout the Body

December 2, 2016 by Valentin Tissot, M.D.

Dr. Valentin Tissot (CHRU, Brest, France) presents cases throughout the whole body that demonstrate that Simultaneous Multi-Slice (SMS) helps to accelerate diffusion-weighted imaging in almost all clinical cases where DWI is commonly applied. Robust results and good image quality can be achieved with an SMS factor of 2, which allows one to achieve near 2-fold acceleration. He also shows that ADC values are highly reproducible between the conventional and the accelerated technique. [...]
