Interpretation

Not medical advice. Structural data only.

Overall Assessment

Your total thalamus volume is 14.02 cm3 (0.83% ICV) with near-perfect bilateral symmetry (+1.00% asymmetry). The QC score of 0.94 indicates excellent segmentation quality.

Good News: The thalamus as a whole is well-proportioned and symmetric, indicating healthy relay station function for sensory and motor signals.

Notable Asymmetry Findings

Two nuclei show significant asymmetry patterns:

MTN (Mammillothalamic): -72.34% asymmetry (left dominant). This is the smallest nucleus (0.02 cm3), so small absolute differences create large percentages. The MTN is part of the Papez memory circuit - extreme asymmetry here may reflect normal anatomical variation in this tiny structure rather than pathology.

LGN (Lateral Geniculate): +16.06% asymmetry (right dominant). The LGN is the primary visual relay - mild asymmetry here is common and may relate to ocular dominance or visual processing lateralization.

Nucleus Functions

Primary Nuclei: PN (visual attention), ISN (integration), VLPN (motor/cerebellar), MN (executive/memory), VPLN (somatosensory), VAN (motor planning).
Relay Nuclei: LGN (vision), MGN (hearing), CN (pain), VLAN (motor), AVN (memory), HN (reward), MTN (memory circuits).

Caveat: DeepThalamus segments 13 individual nuclei, some extremely small (MTN ~0.02 cm3). Small structures have higher measurement variability, so extreme asymmetry percentages should be interpreted with caution. The QC score of 0.94 suggests reliable overall segmentation.
