Diffusion-weighted images acquired using single-shot echo-planar imaging (ss-EPI) often have a low resolution and are limited by blurring and distortion. This study investigated the use of MUSE (multiplexed sensitivity encoding), a multi-shot segmented-EPI technique, in the detection and characterisation of breast cancer. MUSE showed an improvement in image quality and an increased separation of malignant from benign lesions using the normalised apparent diffusion coefficient (ADC).
