A comparison of two diffusion weighted imaging sequences, Echo Planar Imaging (EPI) and Half fourier Aquisition Single shot Turbo spin echo (HASTE), was conducted in the prostate. EPI, which is currently the main DWI method, is highly susceptible to artifacts, namely magnetic susceptibility and chemical shift. We propose to use a HASTE sequence, which is less affected by these artifacts, to gain more reproducible Apparent Diffusion Coefficient (ADC) values and increase ADC map quality. Advancements in this area will lead to more accurate prostate cancer localisation.
