WebJun 6, 2024 · Occasionally, the DWI signal will persist long after the acute stroke – a phenomenon called “shine through.” To avoid mistaking DWI shine through for acute stroke, neurologists and radiologists refer to a second MRI sequence, called the ADC map. This ‘confirms’ acute stroke by appearing dark in the corresponding area of diffusion ... WebHowever, because DWI sequences contain T2 weighting, areas within the brain with high inherent T2 signal intensity can also show increased signal on DWI sequence, so-called T2 shine-through. To distinguish T2 shine-through from true restricted diffusion, consult the apparent diffusion coefficient (ADC) map. Areas of T2 shine-through will be ...

WebThis process is referred to as “T2 shine-through,” and can be mitigated with higher b values. 2 The most common use of DWI is in the setting of acute ischemia by determining the presence of restricted diffusion from cytotoxic edema secondary to cell death. We will discuss other central nervous system (CNS) abnormalities where restricted ... WebT2 shine-through refers to high signal on DWI images that is not due to restricted diffusion, but rather to high T2 signal which 'shines through' to the DWI image.T2 shine through occurs because of long T2 decay time in some normal tissue.
