Doppler sonographic study of common carotid artery and jugular vein blood flow in Labrador dogs
Bibliographic record
Abstract
In the present study, Doppler sonographic findings of common carotid artery (CCA) and external jugular vein (EJV) blood flow in normal as well as neurological deficit Labrador dogs were evaluated. In the first part of the study, 12 apparently healthy adult Labrador dogs (in two groups; group I animals aged 2-6 yr, group II animals aged 6-10 yr) were subjected to B-mode and Doppler ultrasonography of the CCA and EJV. Doppler ultrasonography was performed in all animals without sedation in lateral decubitus position using 7.5 MHz linear transducer. The mean values CCA diameter (D), peak systolic velocity (PSV), end diastolic velocity (EDV), pulsatility index (PI), resistive index (RI) and velocity (V) differed significantly between the groups I and II. No differences were found between genders or vessel sides of same age group animals. In the second part of the study, five dogs showing variable neurologic signs were subjected to Doppler sonographic examination; the neurological conditions were broadly categorized as inflammatory conditions, upstream stenosis of CCA, downstream stenosis of CCA and jugular venous reflux.

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.
