Abstract
Objectives: This research's aim was to determine Ontarian sonographers’ awareness of vasa previa (VP). Particularly, their knowledge of the risk factors for and methods used to exclude the presence of VP. This research also endeavoured to establish if imaging the placental cord insertion site is routine practice in workplaces in Ontario. Methods: An on-line survey was disseminated to 1,200 sonographers in Ontario, Canada who were members of the Canadian Society of Diagnostic Medical Sonographers (CSDMS). In total, 213 sonographers participated. Results: Analysis of open questions regarding risk factors for VP revealed both themes that were indeed associated with VP and those that were not. Succenturiate/bi-lobed/ accessory placenta was indicated as a risk factor for VP by 173 (81.2%) of participants. Velamentous cord insertion was chosen by 169 (79.3%) and low-lying second trimester placenta followed with 154 (72.3%). Pregnancies obtained via in-vitro fertilization were selected by 72 (33.8%) participants. There was more congruence regarding techniques used to exclude VP. Two-hundred and four (95.8%) participants stated they would utilize colour Doppler and 181 (85.0%) indicated that transvaginal imaging would be their method of choice to exclude VP. The placental cord insertion site is imaged routinely by 151 (70.9%) of the participating sonographers. Conclusions: It is apparent that an overall awareness of VP does not exist among sonographers participating in this study. There is no statistically significant relationship between increased awareness and length of career, workplace, or skill set. It appears that increased awareness among sonographers is indiscriminate.

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 it
