Pancreatic imaging is an essential tool in the early diagnosis and staging of pancreatic disease. This review analyzes the most recent advances in pancreatic imaging. The specific modalities discussed include helical computed tomography (HCT) and multislice CT (MSCT), CT angiography, magnetic resonance imaging (MRI), magnetic resonance cholangiopancreatography (MRCP), and positron emission tomography (PET). At present, MSCT is generally viewed as the most efficient modality for initial detection and staging of pancreatic carcinoma, with an accuracy rate of about 95% to 97% for initial detection and virtually 100% for staging. CT is also the initial imaging modality used in evaluation of acute pancreatitis. However, recently, MRI has been viewed increasingly as a more precise diagnostic tool in this subgroup of patients. MRCP has been accepted as the primary imaging technique in the diagnosis of chronic pancreatitis. PET imaging, on the other hand, has an increasing role in the staging of pancreatic carcinoma, for which it may be the modality of choice in detection of extrapancreatic metastasis.
胰腺成像在胰腺疾病的早期诊断和分期中是一项重要工具。本综述分析了胰腺成像的最新进展。所讨论的具体成像方式包括螺旋计算机断层扫描(HCT)和多层螺旋CT(MSCT)、CT血管造影、磁共振成像(MRI)、磁共振胰胆管造影(MRCP)以及正电子发射断层扫描(PET)。目前,MSCT通常被视为胰腺癌初始检测和分期最有效的成像方式,初始检测的准确率约为95%至97%,分期准确率几乎达100%。CT也是用于评估急性胰腺炎的初始成像方式。然而,近来,MRI在这类患者亚组中越来越被视为一种更精确的诊断工具。MRCP已被公认为慢性胰腺炎诊断的主要成像技术。另一方面,PET成像在胰腺癌分期中的作用日益增加,在检测胰腺外转移方面它可能是首选的成像方式。
