Reversible Posteri,T2-effects can be mathematically removed from the DW image to create a pure parametric image of apparent diffusion coefficients (the "ADC Map"). The ADC Map is created by dividing the signal from the trace-DW image (SDWI) by the signal (So) from,As discussed in the last Q&A, lesions bright on diffusion-weighted (DW) images do not all restrict diffusion. Some have prolonged T2 values that spill over into the DW image, a phenomenon known as T2-"shine through". To sort this out, the AD,Chemists in the early 1930's recognized that the measured diffusion rates of dyes and other small molecules were highly dependent both on the nature of the media studied and on experimental conditions. Recognizing these limitations, they began to use , Methods. 117 work-ups in 98 patients with cerebral infarction (12 hyperacute, 43 acute, 29 subacute, 10 steady, and 23 chronic infarctions) were imaged with both conventional MRI and diffusion weighted imaging.

Author information: (1)Department of Radiology, ,跳到 ADC image - An apparent diffusion coefficient (ADC) image or an ADC map is an MRI image that more specifically shows diffusion than conventional DWI, by eliminating the T2 weighing that is otherwise inherent in conventional DWI. ADC imaging does so by
