Thank you very much, that's the solution :)
I guess this happens due to the way the scans were adquired.
I tried SPM8's Dicom Import, and it seems it's working, I get the same
results, but with some errors:
Warning: D:\DICOM\09112215\35460000\25390224: dimension problem [Num
Images=29, Num Cols=16, Num Rows=16].
