CP-1407 Add diffusion tractography related sites STATUS Assigned Date of Last Update 2014/08/12 Person Assigned David Clunie Submitter Name James Reuss Submission Date 2014/05/06 Correction Number CP-1407 Log Summary: Add diffusion tractography related sites Name of Standard PS 3.16 2014a Rationale for Correction: White matter tracts and related structures (as represented with MR diffusion tensor tractography) need to be described with a higher degree of anatomical precision as well as a different concepts (tracts that span regions) than is currently defined for other applications such as segmentation. Correction Wording:
Add new Context Groups to DICOM PS 3.16 Annex B Context Groups as follows:
