Dear Fengnong, thanks for your explanations about the data and your processing, from the screenshot in Point 3 I see that you don’t have the ‘Data Manager’ view open, this is the one I meant with the right click and the context menu. The overview of the main features of the application can be found in the online user manual: http://docs.mitk.org/nightly/MITKUserManualPage.html For your data: For IVIM evaluation, you generally need multiple volumes at different diffusion weighting. According to the information shown on the picture, your data contain of 9 volumes with 18 axial slices each, the first volume is also displayed. When you open the DataManager View, you will be able to step through the 9 volumes of the image using the ‘Component’ slider there. For your final question, I still don’t understand what you mean by ‘best slice’. For a proper IVIM Evaluation, you need the information from all (9 in your case) volumes, the selection of a region over which the IVIM-related measures are computed depends on the structure you want to evaluate. Best, Jan

However, I can't understant what you said, perhaps I am a beginner to use the software. To directly present my question, I made a chart. Please look at the attachment. Thanks again. 2015-10-08 ________________________________ With best regards, Fengnong Chen. ----------------------------------------------------------- KTH Royal Institute of Technology STH School of Technology and Health Alfred Nobels Alle 10 SE-14152 Huddinge Stockholm, Sweden +46 700708477 http://www.kth.se/en/sth ________________________________ 发件人："Hering, Jan" <j.her...@dkfz-heidelberg.de<mailto:j.her...@dkfz-heidelberg.de>> 发送时间：2015-10-06 16:50 主题：RE: [mitk-users] the best slice of IVIM _Fengnong Chen 收件人："fnchen.kth"<fnchen....@gmail.com<mailto:fnchen....@gmail.com>> 抄送："mitk-users"<mitk-users@lists.sourceforge.net<mailto:mitk-users@lists.sourceforge.net>> Dear Fengong Chen, could you please clarify what acquisition sequence do you use (which b-values and what size has the image)? And also what do you mean by denominating a single slice as ‘the best slice’? It looks like the original data (with the 162 slices) is not sorted into volumes by the corresponding b-values. This is the default behavior of MITK when dealing with diffusion-weighted MRI. You see the volume at once and by using the component slider ( in the context menu that appears after a right mouse click on the image node in the DataManager ) you can switch between the different b-values. If my assumptions are correct, you will find your 120th slice in the 8th component as the second slice. However, the numbers you write do not fit into my interpretation as I would expect you to have either 153 slices ( this would mean 9 b-values ) or 170 slices ( 10 b-values ).

Oktober 2015 12:05 To: mitk-users Subject: [mitk-users] the best slice of IVIM _Fengnong Chen Dear all, My research forcus on breast cancer of IVIM. I get the best slice in original MRI-IVIM sequence, for example, the best slice is 120th in total 162 slices. But when I import the sequence into MITK, the axial just show 17 slice as the reason of being combined into a vector. So, my question is how to get the best slice in axial vector ? Thank you very much in advance. 2015-10-06 ________________________________ With best regards, Fengnong Chen. ----------------------------------------------------------- KTH Royal Institute of Technology STH School of Technology and Health Alfred Nobels Alle 10 SE-14152 Huddinge Stockholm, Sweden +46 700708477 http://www.kth.se/en/sth
