      // We can also load the dataset first and then call AddPresStateImageRefByDS 
      dicomDataset.AddPresentationStateImageReference(Path.Combine(LEAD_VARS.ImagesDir, "DICOM", "IMAGE3.dcm"), null, 0);

      DicomElement item = dicomDataset.FindFirstPresentationStateReferencedSeriesItem(); 
 
      string imageRefSOPInstanceUID = dicomDataset.GetPresentationStateImageReferenceSOPInstance(item, 0); 
      Debug.Assert(imageRefSOPInstanceUID != null); 
      DicomElement item1 = dicomDataset.GetPresentationStateImageReference(imageRefSOPInstanceUID); 
      Debug.Assert(item1 != null); 
 
      dicomDataset.Save(Path.Combine(LEAD_VARS.ImagesDir, "DICOM", "PresentationState.dcm"), DicomDataSetSaveFlags.None); 
   } 
   DicomEngine.Shutdown();
