<div dir="ltr"><font face="Tahoma" color="#000000" size="2">Hi all,</font></div>
<div dir="ltr"><font face="tahoma" size="2">I am taking FA and ADC measurements of the Cingulum and Fornix in epilepsy patients using tractography in DTI Studio. I have noticed that the ADC values of the selected fibres in the Cingulum are in the region of
0.0007 but that this measurement only goes to 4 decimal places. In order to detect any differences in ADC across patient groups I would need more decimal places.</font></div>
<div dir="ltr"><font face="tahoma" size="2"></font> </div>
<div dir="ltr"><font face="tahoma" size="2">I have clicked the statistics profile button in the Fiber Statistics window and have gotten a list of ADC values for each slice with a greater number of decimal places (i.e., 7.11e-004 which I assume is 0.000711)
for my tract.</font></div>
<div dir="ltr"><font face="tahoma" size="2"></font> </div>
<div dir="ltr"><font face="tahoma" size="2">So my question is, can I take the mean of all these values in the Statistics Profile window (for a given slice orientation) and use that as my mean ADC value for the selected tract?</font></div>
<div dir="ltr"><font face="tahoma" size="2"></font> </div>
<div dir="ltr"><font face="tahoma" size="2">OR is there an easier way for me to get the mean ADC for a selected fiber tract with a greater number of decimal places?</font></div>
<div dir="ltr"><font face="tahoma" size="2"></font> </div>
<div dir="ltr"><font face="tahoma" size="2">Thanks in advance for your help.</font></div>
