[Insight-users] itk::GDCMImageIO - GetValueFromTag

[David Lambiel]

Hello
Thanks in advance for the help.
I'm extracting some tags from a DICOM image set. Some tags are correct, some
seem to be empty... But I checked with imageJ and they exists.

For example: I'm getting the tags with something like this:

itk::GDCMImageIO::Pointer dicomIO = itk::GDCMImageIO::New();

[...]

std::string patientID;
std::string tagkey = "0010|0020";
dicomIO->GetValueFromTag(tagkey, patientID);
std::cout  << "    Patient ID: " << patientID << std::endl;

std::string patientBirthDate;
tagkey = "0010|0030";
dicomIO->GetValueFromTag(tagkey, patientBirthDate);
std::cout  << "    Patient BirthDate: " << patientBirthDate << std::endl;

[...]

std::string studyInstanceUID;
tagkey = "0020|000D";
bool found = dicomIO->GetValueFromTag(tagkey, studyInstanceUID);
std::cout  << "    Study Instance UID: " << studyInstanceUID << std::endl;

The 2 first are correct, but the third is empty. The getValueFromTag return
me a 0. But imageJ give me for the same set:

[...]
0010,0020  Patient ID: 278579
[...]
0020,000D  Study Instance UID: 1.2.840.41213141111.2.9.3.400025584

So I'm lost. Does someone has an idea where/what is the problem ?
Perhaps I'm missing something, important or dumb...

Thanks
