T2 shine through

Lesion conspicuity is often better on DWI than on ADC maps, which is the reason why DWI images are preferred by many neuroradiologists for clinical image interpretation. DWI alone may be sufficient in most cases, but differentiation from T2 shine-through effects can be difficult, particularly with... 

The resulting DW images has not only diffusion contrast but also T2 contrast (also known as T2 shine through ). In order to remove the T2 weighting, the DW images S is divided by the T2 image (b=0). The exponential image is easily thus derived from (7.1) as ...
