In vivo diffusion attenuation comparison. Typical patient images depicting an invasive ductal carcinoma (IDC), a benign cyst, a high-grade ductal carcinoma in situ (DCIS), and an invasive lobular carcinoma (ILC) acquired with contrast-enhanced T1 weighting (Post contrast) and diffusion weighting. The DESS images show higher resolution and less distortion than the conventional spin-echo EPI diffusion-weighted images (DWI), but with comparable image contrast.
