| [ Summary ] |
Endoscopic ultrasonography (EUS) is highly capable of spatial resolution, and is a useful examination method for diagnosing pancreatic diseases. It is particularly useful for the diagnosis of small lesions, or differential diagnosis of cystic lesions, in pancreatic diseases. For pancreatic cancer, diagnostic imaging is achieved in 75.9 % by US, 77.6 % by CT (inclusive of helical CT and MDCT) and 100 % by EUS ; in pTS1, in 50.0 % by US, 41.7 % by CT, in contrast 100 % by EUS. In intraductal papillary-mucinous neoplasm (IPMN), diagnostic imaging of elevated nodules is achieved in 55 - 62 % by US, CT and MRCP, respectively, in contrast with as high as 95 % by EUS. While EUS is a useful examination method for pancreatic diseases, it is important for accurate diagnosis that we are adept in the standard imaging method and master the technique. |
