Тhe Methodology of the Whole-Body Diffusion-Weighted Imaging
Whole body diffusion-weighted imaging (WB-DWI) has wide spectrum of applications in oncology. This method is used for detection of primary malignant tumor and its distant metastases, treatment monitoring and lymphoprolifera-tive disease staging. WB-DWI is an effective and safe diagnostic tool, well-tolerated by patients, with high reproductability and few contraindications. Adequate protocol building is an important condition of successful WB-DWI application. Some parameters of basic pulse sequence have remarkable influence on image quality and contrast. Inadequate technical parameters can drastically compromise the results of examination.The article tackles technical aspects of WB-DWI, data gaining and postprocessing, basic parameters that corre­late with image quality, general artifacts and how to avoid them. The article will probably be interesting for radiolodists who start using WB-DWI.
