May specify trimester if determinable from clinical history or biometry."},"clinicalHistory":{"defaultText":"[Patient-specific — populated at report time]","aiInstructions":"Ask the user for: patient age, sex, presenting complaint, relevant clinical history, and reason for the exam. This section contextualizes the entire report. Always include it."},"comparison":{"defaultText":"No prior obstetrical ultrasound studies available for comparison.","aiInstructions":"If prior studies are mentioned, extract dates and findings.

Selected static images were reviewed.","aiInstructions":"Describe imaging approach (transabdominal, transvaginal, or both). Include any special techniques used (Doppler, M-mode). Keep descriptive but concise."},"findings":{"defaultText":"Single intrauterine pregnancy is identified.","aiInstructions":"Begin with confirmation of pregnancy number and location. Progress through fetal presentation, placental findings, biometry, fluid volume, cardiac activity, and anatomical survey status. Use objective measurements and standardized terminology.","fields":[{"name":"Pregnancy Number and Location","defaultText":"Single intrauterine pregnancy is identified.","aiInstructions":"Document number of gestational sacs and fetuses. Confirm intrauterine location. Note any complications such as heterotopic pregnancy if applicable."},{"name":"Fetal Presentation","defaultText":"Fetal presentation is noted.","aiInstructions":"Document fetal lie and presentation (cephalic, breech, transverse). Include position relative to maternal anatomy if clinically relevant."},{"name":"Placenta","defaultText":"The placenta is normally located and is free of the cervical os.","aiInstructions":"Document placental location (anterior, posterior, fundal, lateral). Specify distance from cervical os in centimeters if measured. Note placental appearance (echogenicity, homogeneity, thickness). Document any abnormalities such as previa, accreta, or infarction if present."},{"name":"Cervical Length","defaultText":"Cervical length is within normal limits.","aiInstructions":"If cervical length is measured, document exact measurement in centimeters. Specify measurement technique (transvaginal preferred).

Include corresponding gestational age equivalent in weeks and days. Compare to expected range for stated gestational age."},{"name":"Head Circumference","defaultText":"Head circumference corresponds to appropriate gestational age.","aiInstructions":"Document exact measurement in millimeters. Include corresponding gestational age equivalent in weeks and days. Note if measurements are concordant with other biometric parameters."},{"name":"Abdominal Circumference","defaultText":"Abdominal circumference corresponds to appropriate gestational age.","aiInstructions":"Document exact measurement in millimeters. Include corresponding gestational age equivalent in weeks and days. This parameter is most sensitive for growth restriction; note any discordance with head measurements."},{"name":"Femoral Length","defaultText":"Femoral length corresponds to appropriate gestational age.","aiInstructions":"Document exact measurement in millimeters. Include corresponding gestational age equivalent in weeks and days. Bilateral measurements if both femurs are evaluated."},{"name":"Estimated Fetal Weight","defaultText":"Estimated fetal weight is appropriate for gestational age.","aiInstructions":"Document weight in grams with margin of error (e.g., ±10%). Include percentile for gestational age. Note if growth is appropriate, restricted, or excessive."},{"name":"Amniotic Fluid Volume","defaultText":"Amniotic fluid volume is normal.","aiInstructions":"Document as normal, decreased (oligohydramnios), or increased (polyhydramnios). If measured, include deepest vertical pocket or amniotic fluid index with exact measurements in centimeters."},{"name":"Fetal Cardiac Activity","defaultText":"Regular fetal cardiac activity is demonstrated.","aiInstructions":"Document fetal heart rate in beats per minute. Specify if rate is normal, tachycardic, or bradycardic. Note regularity of rhythm. Specify imaging method used (M-mode, pulsed Doppler)."},{"name":"Anatomical Survey","defaultText":"Anatomical survey of the fetus is unremarkable.","aiInstructions":"Document if detailed anatomical survey was performed in current study or if previously documented. Note any abnormalities identified in fetal anatomy including head, face, spine, thorax, abdomen, extremities, and umbilical cord. Document number of umbilical vessels if evaluated."},{"name":"Interval Growth","defaultText":"Interval growth assessment is not applicable.","aiInstructions":"If prior studies exist, document interval change in biometric parameters. Specify dates of prior study and current study. Note if growth is appropriate, restricted, or accelerated. Calculate growth percentiles if applicable."}]},"impression":{"defaultText":"Single intrauterine pregnancy with appropriate growth for stated gestational age.","aiInstructions":"Synthesize findings into concise clinical summary. Include: (1) pregnancy number and viability; (2) composite gestational age in weeks and days; (3) assessment of growth (appropriate, restricted, or excessive); (4) relevant findings (placental location, amniotic fluid status, anatomical abnormalities if any); (5) estimated date of delivery; (6) interval growth assessment if applicable; (7) any recommendations for follow-up.
