Abdominal applications of diffusion-weighted magnetic resonance imaging: Where do we stand

Figure 2 Neuroendocrine metastases to liver. A: Axial arterial phase post contrast T1-weighted (T1W) gradient recalled-echo; B: Diffusion-weighted image (DWI). Only 3 enhancing metastatic lesions are seen on the post contrast T1W image. DWI increases conspicuity of these lesions and also shows many more bilobar high signal metastatic lesions with impeded diffusion.
