DICOM Structured reports are DICOM SOP Instances, organised just the same way as images etc., but which hold reports rather than images. They are typically therefore only a few kilobytes in size. They contain all the same indexing information as images, and therefore fit into the standard 4 level DICOM Hierarchy, complete with their own “psuedo-modality” of SR.
The Well-Known UIDs are Static Instance UID mostly used in normalised operations. The following is a list of all UIDs in DICOM
Many people wish to obtain a list of studies of a particular type (modality) - CR, MR etc.
Secondary Capture Images Composite Instances which are the “lowest common denominator” images available in DICOM.
The Modality Performed Procedure Step Service, commonly known as MPPS, provides a mechanism for modalities to pass information about the imaging they are performing back to the RIS and/or PACS.
