OBJECTIVE In this article, we present the basic principles of diffusion-weighted imaging (DWI) that can aid radiologists in the qualitative and quantitative interpretation of DW images. However, a detailed discussion of the physics of DWI is beyond the scope of this article. A short discussion ensues on the technical aspects of performing DWI in the body. The emerging applications of DWI for tumor detection, tumor characterization, distinguishing tumor tissue from nontumor tissue, and… 

The role of diffusion weighted magnetic resonance imaging in oncologic settings.

Oncologic applications of diffusion-weighted-imaging in the parts of the body are presented and it is thought that DWI can be added to conventional magnetic resonance imaging (MRI) sequences.

Diffusion-Weighted Breast Imaging: Beyond Morphology

The main technical issues associated with the implementation of DWI in the clinical setting are detailed and potential approaches for obtaining good-quality images are presented, including the concept of apparent diffusion coefficient (ADC).

Diffusion-weighted imaging of the breast: principles and clinical applications.

Standardization of diffusion-weighted imaging parameters is needed to allow comparison of multicenter studies and assessment of the clinical utility of diffusion, weighting and ADC values in breast evaluation.

Diffusion-weighted imaging in pediatric body MR imaging: principles, technique, and emerging applications.

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.

Whole-body-MR-diffusion weighted imaging in oncology.

WB-DWI has a strong diagnostic potential regarding the evaluation of bone marrow and its diseases and as thus, tumor detection and therapy monitoring of bone metastasis is of particular interest.

Diffusion-weighted imaging of pancreatic cancer.

It is still unclear whether and how DWI could be helpful for identification, characterization, prognostic stratification and follow-up during treatment, but up-to-date literature data regarding the applications of DWI and IVIM to PDACs are reviewed.

Principles and applications of diffusion-weighted imaging in cancer detection, staging, and treatment follow-up.

Diffusion-weighted imaging has many applications in oncologic imaging and can aid in tumor detection and characterization and in the prediction and assessment of response to therapy.

Role and application of diffusion-weighted imaging in evaluation of prostate cancer

DWI demonstrates the restriction of diffusion and the reduction of ADC values in neoplastic tissue and improves the diagnostic accuracy in lesion characterization and can be a useful adjunct to the established dynamic contrast-enhanced-MRI.

Functional MRI: DWI and DCE-MRI

DCE-MRI is a technique that evaluates the microstructural circulation of biological tissues and can be used to evaluate changes in the vascular environment of tumors following therapy with anti-angiogenic agents and has potential to allow earlier detection of tumor response and may prognosticate outcome in some tumors.

Practical issues to help radiologists optimize the use of DWI to evaluate tumors in the body are discussed, including breath-hold DWI, multiple-acquisition non-breath-holdDWI, and diffusion-weighted whole-body imaging with background body signal suppression (DWIBS).

Ultrafast MR imaging of the abdomen: echo planar imaging and diffusion-weighted imaging.

Even though there are many difficulties that must be solved for diffusion-weighted imaging, a more wide application of this technique is expected through technologic improvement.

Usefulness of diffusion‐weighted MRI with echo‐planar technique in the evaluation of cellularity in gliomas

Diffusion‐weighted MRI with EPI is a useful technique for assessing the tumor cellularity and grading of gliomas and is useful for the diagnosis and characterization ofgliomas.

Imaging and targeted agents in gastrointestinal cancers: overview on perfusion- and diffusion-weighted magnetic resonance imaging and angiogenesis inhibitors

The background, basic principles and potential applications of perfusion- and diffusion-MRI for follow-up of treatment with angiogenesis inhibitors are discussed.

A comparative evaluation of a RARE-based single-shot pulse sequence for diffusion-weighted MRI of musculoskeletal soft-tissue tumors

Diffusion-weighted images of the mRARE sequence were less distorted than those acquired with the single-shot EPI sequence, and provided more anatomic information, since the muscle and fat signals were considerably higher.

Diffusion-weighted MR imaging in the evaluation of renal tumours.

W MRI of the kidney seems to be a reliable means for differentiating normal renal parenchyma from different renal tumors, and ADC values of cystic renal cell carcinoma were higher than those of clear cell carcinomas.

Diffusion-weighted whole-body imaging with background body signal suppression (DWIBS): features and potential applications in oncology

The recently introduced concept of “diffusion-weighted whole-body imaging with background body signal suppression” (DWIBS) now allows acquisition of volumetric diffusion- Weighted images of the entire body.

Comparison of quantitative T2 mapping and diffusion‐weighted imaging in the normal and pathologic prostate

Evidence suggesting that diffusional anisotropy is present in normal prostatic tissue is also detailed, with significant differences noted between the z‐component and both the x‐ and y‐components of the ADC for peripheral zone and central gland.

Diffusion-weighted single-shot echoplanar MR imaging for liver disease.

Measurement of ADC has good potential for characterizing liver lesions, but the calculated ADCs could be affected by the magnitude of the maximum b value.
