TL;DR: Three-dimensional DWIBS can be obtained with this technique, which may allow us to screen for malignancies in the whole body through diffusion weighted whole body imaging with background body signal suppression.

Abstract: In applying diffusion-weighted whole-body imaging with background body signal suppression (DWIBS) technique, DW-MR images are acquired during free breathing, which results in images with high signal-to-noise ratio using relatively thin image sections (4–5 mm). Image acquisition during free breathing is possible because bulk tissue motion, including respiratory motion, may be considered as types of coherent motion, which do not result in significant signal loss unlike intravoxel incoherent motion, which reflects random water motion at a cellular level. The concept of DWIBS allows handling of the acquired images as a volumetric dataset and it exploits both prolonged T2 relaxation time and impeded diffusion that the majority of solid lesions (both benign and malignant) exhibit as mechanisms for image contrast, which is used for clinical evaluation of diseases.

TL;DR: MRI is a rapid and sensitive method, particularly in pediatrics, for detecting and monitoring multifocal lesions in the body as a whole and utilized for both oncologic and non-oncologic indications.
11C-choline PET/CT and whole-body MRI including diffusion-weighted imaging for patients with recurrent prostate cancer
Hinrich Wieder,Ambros J. Beer,Konstantin Holzapfel,Martin Henninger,Tobias Maurer,Sarah Schwarzenboeck,Ernst J. Rummeny,Matthias Eiber,Jens Stollfuss +8 more
TL;DR: 11C-choline PET/CT was superior in the detection of local recurrence and bone metastasis on a regional basis and whole-body MRI including DWI cannot serve as alternative imaging modality for restaging prostate cancer.
Evaluation of dual-source parallel RF excitation for diffusion-weighted whole-body MR imaging with background body signal suppression at 3.0 T

TL;DR: Dual-source parallel RF excitation improved image quality of DWIBS at 3.0 T with respect to signal homogeneity and fat suppression, reduced scan time by approximately one-third, and did not influence the measured ADC values.

TL;DR: Fa values may play a supportive role in the imaging of liver lesions because they are able to obtain not only apparent diffusion coefficients (ADCs) but also fractional anisotropy (Fa) values by using DTI.

TL;DR: The problem of image reconstruction from sensitivity encoded data is formulated in a general fashion and solved for arbitrary coil configurations and k‐space sampling patterns and special attention is given to the currently most practical case, namely, sampling a common Cartesian grid with reduced density.

Diffusion-weighted MR imaging of the brain.
TL;DR: Because stroke is common and in the differential diagnosis of most acute neurologic events, diffusion-weighted MR imaging should be considered an essential sequence, and its use in most brain MR studies is recommended.

Diffusion weighted whole body imaging with background body signal suppression (DWIBS): technical improvement using free breathing, STIR and high resolution 3D display.
TL;DR: In this article, the authors examined a new way of body diffusion weighted imaging (DWI) using the short TI inversion recovery-echo planar imaging (STIR-EPI) sequence and free breathing scanning (diffusion weighted whole body imaging with background body signal suppression; DWIBS) to obtain three-dimensional displays.
