Description
Summary:[...]the considerable overlap between benign and malignant masses has hampered tumor characterization with DWI throughout the body [2]. [...]while we admit that DWI is helpful, the sequence has limitations and disagree that DWI is “the most essential sequence”. [...]although sometimes useful diagnostically, DWI in many parts of the body suffers from considerable artifacts, mostly related to magnetic susceptibility and physiologic motion. [...]in the thorax and abdomen, where respiration and air-bone interfaces mar image quality, it can be a considerable technical challenge to obtain satisfactory image quality with diffusion. [...]the optimal sequence parameters in these body parts, especially the magnitude of diffusion weighting (b-value), have not been established.
