How to read private tag value

[MENG HO]

I tried to read the private tag value from a dicom file. It has a private block (300B, 00XX) and private attribute (300B, XX02). VR = FL, VM = 1.

 

I tested with several ways (like add the tag in dicom dictionary and private dictionary) and none of them worked.

What I understand from your question is you want to read the value of private tag

Following are two ways

var tag = DicomTag.Parse("2001,107B");

var value = file.Dataset.Get<string>(tag);

If above will not work (why ??? )

try below

var tag = DicomTag.Parse("2001,107B");  

var item = (from dicomItem in file.Dataset

            where dicomItem.Tag.Group == tag.Group &&   dicomItem.Tag.Element == tag.Element

            select dicomItem as DicomElement).SingleOrDefault();

var value = item==null?string.Empty:item.Get<string>();
