The Importance of Postprocessing and Data Analysis for Breast Diffusion Weighted Imaging The role of magnetic resonance imaging (MRI) in breast cancer diagnosis and management is evolving as a supplemental screening tool for high-risk populations. Nowadays, a myriad of magnetic…
Data Acquisition Essential Elements of Calibration (B 0 And B 1 ) Most breast diffusion scans are performed with fat suppression and an echo-planar imaging (EPI) readout. Both these elements have optimal performance with uniform B 0 (magnet) and B…

As discussed in detail in earlier chapters of this book, diffusion-weighted imaging (DWI) is a powerful tool in the multiparametric assessment of breast lesions with magnetic reconace imaging (MRI) and can provide decisive information for initial detection and classification of…
Overview of Breast Diffusion-Weighted Imaging Standardization Efforts Given the rapid advances in diffusion-weighted imaging (DWI) technology and the multiple parameters influencing quality of breast DWI acquisition and analysis, harmonization of breast DWI protocols necessitates coherent standardization efforts by physicians, researchers,…
Diffusion-weighted imaging (DWI) is an magnetic resonance imaging (MRI) technique where the mobility of water molecules diffusing in tissue contributes to the image contrast. Sensitivity to diffusion is achieved by adding a pair of symmetrical diffusion sensitizing gradients to a…
Diffusion-weighted imaging (DWI) is a promising approach for breast magnetic resonance imaging (MRI), both as a way to complement or to replace contrast-enhanced MRI. DWI measures diffusive motion, which is quantified by diffusivity, D , often measured in mm 2…
Basic Concept of Diffusion-Weighted Whole Body Imaging With Background Body Signal Suppression (DWIBS) Since the 1990s, diffusion-weighted imaging (DWI) has revolutionized the diagnosis of acute cerebral infarction, making it possible for patients to receive thrombolytic agents in emergency situations and…
Background Personalized medicine is yielding increasingly precise treatment and prevention strategies for groups of individuals based on their genetic makeup, environment, and lifestyle, as enabled by approaches including genomics, transcriptomics, proteomics, metabolomics, and so forth. In oncology, the goal of…
Diffusion tensor imaging (DTI) is a widely applied quantitative magnetic resonance imaging (MRI) approach to characterize tissue microstructure throughout the body. In addition to quantifying the amount of water diffusion hindrance by tissue, DTI also captures the orientational bias (anisotropy)…
