Diffusion-weighted MR Imaging of the Brain

This new edition of this practical-minded text on diffusion-weighted MR imaging has been completely revised and updated. It includes diffusion tensor imaging in each chapter and a new chapter on "Diffusion-Weighted Imaging of Scalp and Skull Lesions."

This practical-minded text helps the radiologist and the clinician understand diffusion-weighted MR imaging. The book's 15 chapters range from basic principles to interpretation of diffusion-weighted MR imaging and specific disease. In this second edition, diffusion tensor imaging (fractional anisotropy, color map and fiber tractography) is covered and a new chapter, on "Diffusion-Weighted Imaging of Scalp and Skull Lesions," is included. The volume is updated by newly added cases accompanied by radiological and pathological images along with the most recent references. It is aimed at all those who are involved in neuroimaging, including: residents, fellows, staff, as well as neurologists and neurosurgeons. Diffusion-weighted MR imaging is widely accepted as a means to identify acute infarction but also to differentiate many other pathologic conditions. Understanding diffusion-weighted imaging is important for radiologists, neurologists, neurosurgeons as well as radiology technologists.
