Q: How is an intraoperative Ultrasonography performed?


A: liver resection with ultrasound guidance is different from an intervention without ultrasound guidance because it helps direct the dissection of the organ, which would otherwise not be covered.   The example that best fits this description is a submarine that sails without sonar and one that uses sonar guidance. The first one follows a route that avoids approaching dry land or a coast, yet it still involves the risk of crashing into other boats. The second one always knows where it is going and if the route it is following is the one intended to be followed. This is the importance of ultrasound guidance.
