On the other hand, the high b value images are strongly diffusion-weighted but have lower signal-to-noise ratio (SNR). The diffusion sensitivity is also affected by per-fusion when low b values are used, produc-ing higher ADC values.

WebSep 1, 2016 · Diffusion-weighted MRI (DWI) depends on how the microenvironment affects the Brownian motion of the water, using ADC map as the quantitative measurement. Low ADC Values can be calculated in densely cellular tissues or those with cellular swelling and high ADC values can be calculated in acellular regions (3). WebThe ADC pixel values together form the ADC map. On a half logarithmic scale, the signal decay delivers a straight tilted line whose slope provides the ADC. The faster the signal decay the steeper the slope and the higher the ADC. The Diffusion image (b 1000) below dis-plays reduced diffusion as hyperintense (brighter pixels); in contrast the ...
