High b-value Diffusion-weighted Imaging in Normal and Malignant Peripheral Zone Tissue of the Prostate: Effect of Signal-to-Noise Ratio

Abstract

Under the same imaging conditions, measuring ADC using a high b-value (2,000 s/mm2) in a monoexponential model has little diagnostic advantage over using the standard b-value (1,000 s/mm2) in discriminating malignant from normal prostate tissue.
