3. 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.

5. 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.

6. 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.
