Fig. 1 A comparison of two EUS orientations: radial and linear imaging of esophageal cancer. The large arrow points to the muscularis propria. The point of maximal tumor invasion is noted with a small arrow.

Fig. 2 An algorithm for the use of EUS in patients with a submucosal lesion or thickened gastric folds. The use of this algorithm results in a decreased need for CT scanning and has been proven to be cost-effective.

Fig. 3 An example of a staging algorithm for gastroesophageal malignancies. EUS is used to provide highly accurate tumor and nodal staging. Gastroenterology 1998 115, 1577-1583DOI: (10.1016/S0016-5085(98)70039-3) Copyright © 1998 American Gastroenterological Association Terms and Conditions
Fig. 4 A staging algorithm for pancreatic masses. EUS is used to diagnose and stage suspected intrapancreatic masses seen on CT scan. The use of EUS in the staging of pancreatic cancer has been shown to decrease the frequency of unsuccessful pancreatic resections.

Fig. 5 An algorithm for diagnosing common bile duct stones in noncritically ill patients. By decreasing the need for ERCPs, EUS can reduce the cost of the evaluation of these patients.

Fig. 6 An example of a pancreatic head mass (M) surrounding the bile duct that has been stented (stent). A fine-needle aspirant was obtained and was diagnostic of pancreatic adenocarcinoma.
