Publicationdate November 3, 2012Cystic pancreatic lesions are increasingly identified due to the widespread use of CT and.Most of these cysts are incidental findings and are benign or low-grade neoplasms.The characterization and management of these cysts is a dilemma since there is a significant overlap in the morphology of benign and premalignant lesions.MR is the imaging study of choice to both characterize and follow these pancreatic cysts.In many cases these lesions remain undetermined and guidelines are needed for follow up and management.by Marc Engelbrecht, Jennifer Bradshaw and Robin Smithuis发表于2012年11月3日胰腺囊性病变广泛应用于CT和MR大多数囊性病变是被偶然发现的,多为良性或低度恶性肿瘤。
由于在良性和癌前病变的形态极其相似,因此对于这些囊性病变的处理处于两难的困境。
选择和遵循这些胰腺囊肿的影像学研究。
在许多情况下,一些病变仍然未制定相关指南来进行跟踪和处理。
