If you just wanna common use, such as extracting sequence from Siemens IMA (DICOM). I don't suggest you buy some expensive so-called professional softwares.
For myself, I prefer to those DICOM reader SDKs whose processing way is much simpler and faster.
Or you can just try the free trials on the web. However, the free ones do not have so many functions.
It's quite confusing...Right?
But if you are looking for professional help, the professional software is always the best choice.
