This image can only be read with an early gdcm 1.2.0 version. It is fairly difficult to re-read since it suffer from two bugs at the same time: 1. VR=UN fields have their Value Length encoded on 2 bytes instead of 4 2. within a SQ some private tag, are encoded as implicit (should be explicit) For instance: S 0008|1110 [SQ] [Referenced Study Sequence] | --- SQItem number 0 | V fffe|e000 [UL] [Item] | V 0008|1150 [UI] [Referenced SOP Class UID] [1.2.840.10008.3.1.2.3.1 ] ==> [Detached Study Management SOP Class] | V 0008|1155 [UI] [Referenced SOP Instance UID] [1.2.826.0.1.2112370.8.1.31823827] | V fffe|e00d [UL] [Item Delimitation Item] | --- | V fffe|e0dd [UL] [Sequence Delimitation Item] S 0008|1111 [SQ] [Referenced Performed Procedure Step Sequence] | --- SQItem number 0 | V fffe|e000 [UL] [Item] | V 0008|0005 [CS] [Specific Character Set] [] | V 0008|0012 [DA] [Instance Creation Date] [20061020] | V 0008|0013 [TM] [Instance Creation Time] [153950] | V 0008|0014 [UI] [Instance Creator UID] [1.3.46.670589.11.8576.5 ] | V 0008|1150 [UI] [Referenced SOP Class UID] [1.2.840.10008.3.1.2.3.3 ] ==> [Modality Performed Procedure Step SOP Class] | V 0008|1155 [UI] [Referenced SOP Instance UID] [1.3.46.670589.11.0.0.11.4.2.0.8576.5.2300.2006102012350701183 ] | V 0020|0013 [IS] [Instance Number] [0 ] | V 2005|0014 [LO] [gdcm::Unknown] [Philips MR Imaging DD 005 ] | B 2005|1406 [ ] [gdcm::Unknown] [gdcm::Binary data loaded;length = 2] | V fffe|e00d [UL] [Item Delimitation Item]
