Abstract
OBJECTIVE: The objective of this study is to evaluate the sensitivity of routine trans vaginal ultrasound (TVUS) compared to expert-guided transvaginal ultrasound (ETVUS) for the diagnosis of endometriosis. METHODS: A retrospective chart review performed at a Canadian tertiary center specializing in the diagnosis and management of endometriosis. All cases with surgically confirmed endometriosis and an ETVUS completed at a single center were included for review and compared to routine TVUS performed for the same indication. RESULTS: Forty cases met the inclusion criteria. Mean patient age of the study population at first surgical diagnosis was 31.2 ± 6.9 years. Dysmenorrhea (76.9 %) and chronic pelvic pain (74.3 %) were the most common presenting symptoms. Sensitivity of routine TVUS was 25 % (10/40), compared to 78 % (31/40) with ETVUS, (P < 0.01). Comparisons were made based on site of disease. Routine TVUS and ETVUS detected bladder involvement in (0/40) vs. 5 % (2/40); ureter (0/40) vs. 7.5 % (3/40); ovary 25 % (10/40) vs. 72.5 % (29/40); retrocervical area (0/40) vs. 60 % (24/40), rectosigmoid 5 % (2/40) vs. 77.5 % (31/40), respectively. Specific endometriotic lesions recognized by TVUS versus ETVUS, were: ovarian endometriomas in 25 % (10/40) vs. 45 % (18/40), adhesions leading to abnormal anatomy in 2.5 % (1/40) vs. 77.5 % (31/40); endometriotic implants or plaques in 2.5 % (1/40) vs. 70 % (28/40); and endometriotic nodules in 2.5 % (1/40) vs. 35 % (14/40), respectively. Routine TVUS diagnosis relied on the presence or absence of endometrioma (10/10), whereas ETVUS showed additional sites of disease in 97 % (30/31) patients. CONCLUSIONS: ETVUS is more sensitive than routine TVUS to diagnose endometriosis, identifying lesions other than endometrioma and is of assistance in surgical planning and patient counseling.

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
