After I converted DCM to NII, NII’s resolution is low and SCT output is not well. So I wonder if there is any other solutions or what kind of software you used to convert DCM to NII.
I need precise numbers of what is “low” and “high”. What was the resolution on the DCM and on the NII (i.e. voxel size in each dimension)? Please, send me one example of DCM series (not only one sagittal 2D image, but the whole sagittal series). Only sending me the NII is not helpful because I cannot compare the DCM and NII resolution.
Do you have details about the T2*WI protocols?
Here is an example protocol:
do I have to use 3D sequence to obtain DCM?
I’m not sure I understand the question. 2D or 3D acquisition is independent on the output of the scanner. Both will give you a DCM file at the end.
I don’t know why it happens. I suppose it is a result of low quality pictures.
What do you mean by “it”. What is the problem? If you’re talking about the apparent interruption on the coronal view, this is just because you need to navigate across coronal slices. If you are talking about the poor R-L resolution, this is due to your native acquisition resolution (there is nothing I can do about that). One way to mitigate this problem is to resample your image to let’s say 0.8mm isotropic before running propseg.
