Attributes using SV

1 DICOM attribute declares this VR.

Working with SV in integration code

VR-aware transformations are where most DICOM integration bugs hide — truncating a PN's 5-component structure, misaligning OB padding, or dropping leading zeros on IS. Saga IT builds production DICOM pipelines that respect VR semantics across Mirth Connect transformers, DIMSE gateways, and cloud DICOM services.
