The DESS sequence has been proposed to acquire 3D high-resolution, low-distortion diffusion-weighted images in reasonable scan times. In this abstract, we have three radiologists evaluate images acquired with DCE, DWI, and DESS sequences. Radiologists evaluated the visibility of lesions, the image sharpness, the lesion margin, rim signal, and internal setpa. We found that DESS highlighted more lesions than DWI, had better image quality, which made morphology easier to assess.
