Abdomen Sonography: Liver Sonographic Anatomy - Video Lesson

Hey everyone, welcome back to our discussion on the anatomy and physiology of the liver. In a previous lesson, we discussed the liver's location and its key relationships within the abdominal cavity and its internal anatomy. In this lesson, we will focus on the normal sonographic appearance of the liver and surrounding anatomy. So, are you ready to take a look at the liver's structures with sonographic eyes? Let's start with the normal appearance of the liver parenchyma, which can be visualized through subcostal, intercostal, or subxiphoid views. With proper gain and time gain compensation, the liver should appear smooth and homogeneous from anterior to posterior. When compared to the right kidney, the liver's echogenicity should be isoechoic to slightly hyperechoic compared to the right kidney, a helpful reference during scanning. When scanning the liver, there are several key landmarks that help with orientation and assessment. The main lobar fissure
