CP-1407 Add diffusion tractography related sites STATUS Nov 2014 Voting Packet Date of Last Update 2014/10/22 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 2014c 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. In addition, the technique is used in various other parts of the body (such as in skeletal and cardiac muscle), and tested using phantoms. The terminology is applicable to both humans and non-human primates, and in future may need to be extended for other research species. Correction Wording:
Add new Context Groups to DICOM PS 3.16 Annex B Context Groups as follows:

SNOMED has codes for the corticobulbar and corticospinal tracts and thalamic radiations in specific regions (e.g., internal capsule), but not generic codes independent of their regional location, so they are not used.

The SLF is distinguished from the AF (even though SNOMED and UMLS treat them as synonymous), per Makris N, et al. "Segmentation of Subcomponents within the Superior Longitudinal Fascicle in Humans: A Quantitative, In Vivo, DT-MRI Study." Cerebral Cortex 15, no. 6 (June 1, 2005): 854–69. doi:10.1093/cercor/bhh186. Hence the SNOMED concept for SLF/AF (T-A2820, 89202009, C0228270) is not used. NeuroNames does not describe the other subcomponents of the SLF than the AF, so DCM codes are assigned.
