[Mristudio-users] ADC values decrease with increasing b-values

[Gustav Andreisek]

Dear All,

 

We imaged a cohort of volunteers at different b-values and determined the
ADC values. We found decreasing ADC with increasing b-values. This would be
in accordance to the literature, as long as we can assume that DTIstudio
does not automatically uses a correction factor for varying SNR at different
diffusion weightings (Dietrich O, Heiland S, Sartor K. Noise correction for
the exact determination of apparent diffusion coefficients at low SNR. Magn
Reson Med 2001; 45:448-453.).

Is that true?

 

Best regards and greetings from Canada,

Gustav
