Dwi adc ミスマッチ
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 ...
