PURPOSE To examine 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. [] Key Method 3) Eleven patients with neck, chest, and abdominal malignancy were scanned with DWIBS for evaluation of feasibility.
Diffusion-weighted whole-body MR imaging with background body signal suppression: a feasibility study at 3.0 Tesla
TLDR
The purpose was to provide a diffusion-weighted whole-body magnetic resonance (MR) imaging sequence with background body signal suppression (DWIBS) at 3.0 Tesla, and a good correlation was found between the metastases as depicted by DWIBS and those as visualized by FDG-PET.
Artifact-robust diffusion-weighted whole-body imaging with background suppression at 3 T using improved turbo spin-echo diffusion-weighted imaging.
TLDR
Direct-coronal TSE-DWIBS is robust against magnetic field inhomogeneity and can be used as a stand-alone treatment for whole-body imaging with background suppression and echo-planar imaging.
Application of Diffusion Weighted Imaging with Background Body Signal Suppression in Brain Neurography
TLDR
By reducing background noises, DWIBS increases the image contrast and the quality of 3D whole-body diffusion weighted images and facilitates the scan speed and reduces the scan time to about 1/3 of the time using conventional technique.
Comparison of diffusion-weighted images using short inversion time inversion recovery or chemical shift selective pulse as fat suppression in patients with breast cancer
TLDR
DWI using STIR may be excellent for fat suppression; and the ADC obtained in this sequence was well correlated with that obtained with DWI using CHESS, which may be useful when the fat suppression technique in DWI use CHESS does not work well.
Diffusion-weighted imaging in pediatric body MR imaging: principles, technique, and emerging applications.
TLDR
Current and emerging applications of DW imaging in pediatric body imaging include tumor detection and characterization, assessment of therapy response and monitoring of tumors, noninvasive detection and grading of liver fibrosis and cirrhosis, detection of abscesses, and evaluation of inflammatory bowel disease.

Diffusion-weighted MR imaging with single-shot echo-planar imaging in the upper abdomen: preliminary clinical experience in 61 patients
TLDR
The mean ADCs obtained with DW imaging were different in each upper abdominal organ and with each pathologic condition, and all DW images showed significantly higher spleen-to-liver SIRs and SIDs than did T2-weighted images.
Sensitivity encoding for fast MR imaging of the brain in patients with stroke.
TLDR
SENSE allowed acquisition of T2-weighted TSE and FLAIR images with image quality and lesion conspicuity that did not differ from those of standard acquisition techniques but in only half the acquisition time.
Diffusion-weighted MR imaging with a single-shot echoplanar sequence: detection and characterization of focal hepatic lesions.
TLDR
It is suggested that diffusion-weighted imaging may be useful for increased detection of HCCs and metastases and in distinguishing these entities from hemangiomas.
Diffusion-Weighted Half-Fourier Single-Shot Turbo Spin Echo Imaging in Breast Tumors: Differentiation of Invasive Ductal Carcinoma from Fibroadenoma
TLDR
Apparent diffusion coefficient measurement using DW-HASTE imaging is helpful in differentiating invasive ductal carcinoma from fibroadenoma, Nevertheless, DW- hasTE imaging has low detectability at present; therefore, more technologic improvement is desired.
Value of T1 and T2 relaxation times from echoplanar MR imaging in the characterization of focal hepatic lesions.
TLDR
Echoplanar-derived T2 times (but not T1 times) are useful for characterizing focal hepatic lesions, and an important use may be to characterize small lesions measuring less than 2.0 cm.
Diffusion-weighted MR imaging for urinary bladder carcinoma: initial results
TLDR
DW images under free breathing enabled the clear detection of the urinary bladder carcinoma, whose ADC values were lower compared with those of the surrounding structure, and may be useful in evaluating tumors invading to the surrounding structures.
[Influence of respiratory motion in body diffusion weighted imaging under free breathing (examination of a moving phantom)].
TLDR
The results indicate that stable motion such as calm respiration does not cause signal loss on DWI, in contrast to intra-voxel incoherent motion (IVIM), and non-breath-hold scanning is feasible.
Sensitivity-encoded diffusion tensor MR imaging of the cervical cord.
TLDR
This approach to diffusion tensor MR imaging of the cervical cord is promising for future, more extensive clinical applications and off-resonance artifacts were notably reduced compared with those of full-FOV EPI sequences.

TLDR
Early data suggest that whole-body turbo STIR MR imaging is as reliable as other conventional imaging studies for staging newly diagnosed small cell tumors in pediatric patients.
