Neuroanatomy Annotation Audit / 神经解剖标注审计
- Audit date: 2026-09-01
- Scope: all 10 existing annotated Atlas images from L01
- Method: identify view → identify landmarks → infer targets independently → consult PPT context → cross-view/reference verification → 1:1 render → re-open final output
- Result: 6 images corrected, 4 images reverified without material correction, 7 image sets
CONFIRMED, 3 image sets retain at least one visiblePROBABLElabel. - Confirmed PPT Annotation Conflicts: none. The corrected defects were in the previous Atlas endpoints/evidence, not confirmed errors in the course PPT. Slide 41 is recorded as non-target-specific because its visible arrows do not establish the four corpus-callosum subdivision endpoints.
Corrected
| Atlas | Correction | Reason |
|---|---|---|
| Corpus callosum midsagittal | Rostrum, genu, body, and thalamus endpoints recentered | The body could be read as pointing into the overlying cingulate/cortical region; endpoints now lie on the white callosal band or thalamic mass. |
| Diencephalon midsagittal | Corpus callosum and thalamus recentered | Anatomical landmark mismatch. |
| Basal nuclei components | Amygdaloid body and contextual thalamic mass recentered | Amygdala had landed on the caudate-tail stalk; thalamus was in an overlap zone. |
| Cortex lateral | Central and lateral sulci recentered | Endpoints had landed on adjacent tissue rather than within the sulcal grooves. |
| Cortex inferior | Midbrain and pons separated | Pons had landed on medulla; midbrain was too close to the pontine junction. |
| Hypothalamic nuclei | Paraventricular and infundibular endpoints refined | Centered within the depicted colored nuclear regions; infundibular boundary remains PROBABLE. |
Verified
- Thalamus–third ventricle coronal: thalamus, third ventricle, lateral ventricle, internal capsule.
- Internal-capsule axial: internal capsule, caudate, lentiform nucleus, thalamus.
- Cerebral-cortex medial: corpus callosum, cingulate gyrus, paracentral lobule, calcarine sulcus, parahippocampal gyrus.
- Basal-nuclei axial: caudate and thalamus confirmed; the low-resolution lentiform and internal-capsule boundaries remain
PROBABLE.
Needs Review
- Basal-nuclei components: contextual red mass labeled
PROBABLE: Thalamus; the PPT does not directly number it. - Basal-nuclei axial:
PROBABLElentiform nucleus and internal capsule because the source image is low resolution. - Hypothalamic-nuclei midsagittal:
PROBABLEinfundibular nucleus because its boundary is not fully separable.
These uncertainty labels do not block the confirmed content. No UNCERTAIN target was rendered as a formal arrow.
