MAGNETOM Flash - September 2009

DWI - September 2009

Siemens Healthcare |  01.09.2009

Diffusion-weighted imaging (DWI) is currently one of the fastest-emerging applications for the precise detection and characterization of lesions in the body. We explore the integration of this method in a variety of clinical scenarios. Prostate imaging, for example, is explored in an article on pre-operative local staging at 3Tesla. In addition, syngo® REVEAL enables us to obtain information about tumor viability, as shown in an extensive case report on a patient with nonsecretory multiple myeloma. DWI techniques can also be used to gather additional information about perfusion within one scan. Background information about the “intravoxel incoherent motion” (IVIM) technique and its clinical relevance in the differentiation of pancreatic lesions are examined in the article by Re et al., German Cancer Research Center.
