This practical, case-focused session equips sonographers with the knowledge and skills to recognise sonographic signs of maternal autoimmune disease and escalate care effectively. Covering common conditions — including antiphospholipid syndrome, systemic lupus erythematosus, anti‑Ro/La–related neonatal lupus and congenital heart block, autoimmune thyroid disease, and immune thrombocytopenia — the talk emphasizes targeted scanning protocols, Doppler techniques (MCA‑PSV, UA, DV), and focused fetal cardiac rhythm assessment. Attendees will see annotated imaging examples and learn standardised reporting language to improve multidisciplinary communication and patient outcomes.
