P96Abnormal trajectory of the anterior cerebral artery. A key finding to the diagnosis of the fetal lobar holoprosencephaly
Bibliographic record
Abstract
Background The prenatal diagnosis of alobar and semi lobar holoprosencephaly is accesible in routine ultrasound. In contrast the diagnosis of lobar holoprosencephaly is still difficult. Prenataly differential diagnosis of lobar holoprosencephaly with septal defects is important for counseling. Case report We describe the shape and trajectory by color Doppler of the anterior cerebral artery in a case of lobar holoprosencephaly. Results The anterior cerebral artery runs under the frontal bones and is a key to the diagnosis of fusion of the two frontal gyri. This has already been described on angiography in children with holoprosencephaly Conclusion This aspect in color Doppler of the anterior cerebral artery is particularly useful in the difficult diagnosis of lobar holoprosencephaly

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
