However, high signal intensity on diffusion-weighted MR images and low apparent diffusion coefficient values (similar to the findings in acute cerebral infarction) were …
WebSep 14, 2024 · The patterns of signal differences on ADC maps reflecting cellularity differences were noted as a heterogeneous signal on DWI and a thick/thin low-ADC-signal rim (high DWI signal). In particular, a thick/thin high rim-signal sign on DWI was statistically correlated with a high-ADC-diff (Table 2, p = .02). The DWI high rim-signal sign refers to ... WebApr 6, 2024 · While the latter cysts were hypointense on T1WI and hyperintense on T2WI also, on DWI, they were hypointense and had high ADC values on ADC map (the same SI as those of CSF) denoting free diffusion.
