Obstetric sonography has become an indispensable tool in the identification of pregnancy and the care of pregnant women. This module teaches you how to prepare for and perform a first trimester ultrasound examination. Including both Learn and Test modes, the online simulator offers three clinical scenarios that cover different aspects of the first trimester scan protocol. Practice the steps of the procedures online as often as you want, until you feel confident.
If you are not a medical student or physician, you may prefer the other version of this module, which includes all the procedural information needed by professionals in other roles: /shop/imaging/sonography/obstetrics/ultrasound-assessment-during-the-first-trimester/
You’ll learn
- to practice, perfect, and test your skills in performing an ultrasound scan during the first trimester
- to better visualize and understand the key structures and components of the embryo at various stages of development during the first trimester, with our 3D model and illustrations
- methods for calculating gestational age during the first trimester of pregnancy
- how to obtain images of the gestational sac, uterus, yolk sac, and embryo via a transabdominal scan, including images of the embryonic heart using M-mode assessment
- how to obtain images of the uterus, endometrium, and gestational sac via an endovaginal scan
- how to differentiate normal and abnormal sonographic appearances during the first trimester
- how to differentiate between intrauterine, ectopic, heterotropic, and multiple pregnancies, including signs, symptoms, and locations
- much more (see Content Details for more specific information)

The SIMTICS modules are all easy to use and web-based. This means they are available at any time as long as the learner has an internet connection. No special hardware or other equipment is required, other than a computer mouse for use in the simulations. Each of the SIMTICS modules covers one specific procedure or topic in detail. Each module contains:
- an online simulation (available in Learn and Test modes)
- descriptive text, which explains exactly how to perform that particular procedure including key terms and hyperlinks to references
- 2D images and a 3D model of applied anatomy for that particular topic
- a step by step video demonstration by an expert
- a quiz
- a personal logbook that keeps track of all the modules the learner has studied and how long
