KW - Basal Ganglia Iron, 2 Gray Out Effect
AB - Objective: Review T2 signal effects on DWI, including a previously undescribed concept of T2 shortening
masking true diffusion restriction on trace DWI images, and the utility of evaluating the ADC/eADC map
in these areas using case examples.
Conclusion: Basal ganglia iron deposition can potentially mask true diffusion restriction when trace DWI
images are viewed in isolation. Review of the ADC/eADC map is helpful for identifying diffusion restriction
in these cases.
