The incidence of pancreatic cystic lesions (PCLs) has been rising due to improvements in imaging. Of these, intraductal papillary mucinous neoplasms (IPMNs) are the most common and are thought to contribute to almost 20% of pancreatic adenocarcinomas. All major society guidelines for the management of IPMNs use size defined by maximum diameter as the primary determinant of whether surveillance or surgical resection is recommended. However, there is no consensus on how these measurements should be obtained or whether a single imaging modality is superior. Furthermore, the largest diameter may fail to capture the complexity of PCLs, as most are not perfectly spherical. This article reviews current PCL measurement techniques in CT, MRI, and EUS and posits volume as a possible alternative to the largest diameter.
由于成像技术的进步，胰腺囊性病变（PCLs）的发病率一直在上升。其中，导管内乳头状黏液性肿瘤（IPMNs）最为常见，被认为几乎占胰腺癌的20%。所有关于IPMNs管理的主要学会指南都将最大直径定义的大小作为推荐进行监测或手术切除的主要决定因素。然而，对于如何获得这些测量值以及单一成像方式是否更具优势，目前尚无共识。此外，最大直径可能无法反映PCLs的复杂性，因为大多数PCLs并非完美的球形。本文回顾了CT、MRI和EUS中目前的PCL测量技术，并提出体积可能是最大直径的一种替代方法。
