The Donald School Journal of Ultrasound in Obstetrics and Gynecology (DSJUOG) publishes quality review articles covering all aspects of ultrasound as it impacts diagnosis and management in the field. As the technology and its applications are constantly improving, there is a need for lifelong learning for all sonologists so that they can optimize their care of gynecologic, maternal and fetal patients on an ongoing basis. The Ian Donald Inter-University School of Medical Ultrasound with its 50 active member nations is proud to support the DSJUOG and provide continuing medical education to sonologists throughout the world. 2018
