Hepatic applications of endoscopic ultrasound: Current status and future directions

Figure 2 Selected computerized tomography scan images showing the liver and its surrounding stomach and duodenum. Both the left lobe and caudate lobe lie in close proximity to stomach (blue colored asterisk indicated gastric lumen) and duodenum (yellow colored asterisk indicated bulb and duodenal lumen), hence providing an easy access during endoscopic ultrasonography (EUS). The caudate lobe and gastrohepatic space can be accessed by EUS while are anatomically difficult to approached by trans-abdominal ultrasound. EUS is limited in its ability to access the portion of the right lobe adjacent to the dome of the diaphragm along with its lateral and inferior portions.
