Diffusion weighted imaging (DWI) is expected to increase diagnostic accuracy of detecting breast cancer. But compared to dynamic MRI, the imaging quality of DWI is poor because of distortion, poor fat suppression, low spatial resolution and so on. Recently DWI using readout segmented echo planner imaging (RS-EPI) is introduced to our institution as work-in-progress sequence and expected to improve imaging quality. We evaluated the imaging quality of 3.0 T diffusion weighted breast MRI using RS-EPI compared to single shot EPI (SS-EPI). Breast diffusion weighted MRI using RS-EPI can reduce imaging distortion and provide better visualization around the nipple.
