The most important part of an ultrasound examination is the initial survey scan. The survey scan first allows the sonographer to obtain an overall impression of the organ of interest. The survey scan is a time to be able to quickly, yet comprehensively, evaluate the organ of interest. The survey scan should also identify areas that require more time to examine during the rest of the ultrasound examination. The sonographer should, at the completion of the survey scan, be able to state whether the organ has pathology or not.  Oftentimes, when a survey scan is not performed, pathology is missed. Recording the survey scan can also allows others that may not have been present during the live scan, to confirm the findings of the sonographer who performed the study. The cases in the following video highlight these principles.
