Diffusion Weighted Whole Body Imaging
 
(DWIBS) This diffusion weighted whole body imaging with background signal suppression provides diffusion weighted contrast throughout the body using a single or multi-station background-suppressed diffusion imaging. DWIBS images are comparable with PET images and provide applications from the visualization of nerve roots and brachial plexus to the detection of lesions throughout the body.

See also Diffusion Weighted Imaging (DWI).

Digital Imaging and Communications in MedicineMRI Resource Directory:
 - DICOM -
 
(DICOM) DICOM is the industry standard for transferral of radiologic images and other medical information between computers. Patterned after the Open System Interconnection of the International Standards Organization, DICOM enables digital communication between diagnostic and therapeutic equipment and systems from various manufacturers.
The DICOM 3.0 standard evolved from versions 1.0 (1985) and 2.0 (1988) of a standard developed by the American College of Radiology (ACR) and National Electrical Manufacturers Association (NEMA). To support the implementation and demonstration of DICOM 3.0, the RSNA Electronic Communications Committee began to work with the ACR-NEMA MedPacs ad hoc section in 1992.
Also Picture Archiving and Communication Systems (PACS), which are connected with the Radiology Information System (RIS) use commonly the DICOM standard for the transfer and storage of medical images.

Digitization
 
Process of conversion of continuous (analog) signals, such as the detected MR signal (voltage), into numbers. This is carried out with an analog to digital converter. There are two kinds of discretization involved: the voltage is only measured (sampled) at particular discrete times, and only voltages within a particular range and separated by a particular minimum amount can be distinguished. Voltages beyond this range are said to exceed the dynamic range of the digitizer.

Quick Overview
Please note that there are different common names for this artifact.
Artifact Information
NAME
Digitization noise, digitizer quantization, low dynamic range
DESCRIPTION
Noise
REASON
Finite voltage resolution of the digitizer
HELP
Larger range of sensitivity
Noise introduced into digitized signals by the finite voltage resolution of the digitizer.
You can see the effects of quantization if the noise level is smaller than the digitizer quantum. If the signal dynamic range is too great, the highest intensities from overloading the digitizer may result in the weaker features being lost in the digitization noise.
mri safety guidance
Image Guidance
This can be resolved by using an analog to digital converter with a larger range of sensitivity or by using techniques to reduce the dynamic range, e.g. suppressing the signal from water in order to detect the signal from less abundant compounds.
