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: ADC histogram analysis shows potential in discriminating progressive from non-progressive disease in patients with mCRC, who underwent whole-body DW-MRI, and the technique can potentially be tested as a response assessment methodology in larger trials.

The long and winding road to translation for imaging biomarker development: the case for arterial spin labelling (ASL)
TL;DR: The case of arterial spin labelling (ASL) is used as an example of the long and winding road to translate a good imaging technique into a clinically relevant imaging biomarker.

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.
Clinical Applications of PET in Oncology
TL;DR: The physics and instrumentation aspects of PET, an analogue of glucose, are described and are being used in diagnosis and follow-up of several malignancies, and the list of articles supporting its use continues to grow.

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.
