ISUOG Women's Health Ultrasound Artificial Intelligence strategy

In light of the recent concerns, highlighted in a news piece by the British Broadcasting Corporation (BBC), in relation to the existence and role of private baby scan clinics, the Safety Committee of the International Society of Ultrasound in Obstetrics and Gynecology (ISUOG) is taking this opportunity to state the Society’s position on the non-diagnostic use of ultrasound in obstetrics performed by non-trained practitioners.

This document provides recommendations regarding the appropriate use of point-of-care ultrasound (PoCUS) in obstetrics and gynecology (Ob/Gyn) in various clinical scenarios encountered by different healthcare professionals (e.g. emergency physicians, obstetrician-gynecologists, midwives, residents and family physicians). The target population consists of patients with Ob/Gyn complications or those needing an interventional procedure for which an immediate bedside sonographic evaluation is helpful.

Read the new ISUOG Practice Guidelines on the use of point-of-care ultrasound (PoCUS) in obstetrics and gynecology in various clinical scenarios that may be encountered by different healthcare professionals.
