摘　　要：作为新兴的功能学成像方法,胰腺CT灌注成像可以定量测量血容量、血流量、毛细血管表面通透性和平均通过时间等灌注参数,进而反映胰腺局部组织病理变化而引起的血流灌注改变。目前胰腺CT灌注成像的研究主要集中在正常胰腺组织、胰腺癌、胰腺炎及胰腺神经内分泌肿瘤等方面,部分灌注参数的研究结果在不同研究中差异较大。但随着多排螺旋CT软硬件技术的发展,胰腺CT灌注成像研究有加速趋势,全面临床应用将成为可能。As a functional imaging technique, pancreatic CT perfusion imaging can provide hemodynamic information of local tissues caused by pathological changes, by mean of measuring parameters BF, BV, PS, MTT, etc. Pancreatic CT perfusion imaging mainly concentrated on the normal tissue of pancreas, pancreatic cancer, pancreatitis and pancreatic endocrine tumors. There were some discrepancies in some perfusion parameters of pancreatic tumors among different studies. Nowadays, with the technological advancements of computed tomography, the studies of pancreatic CT perfusion take on trend of accelerative increase. Accordingly, the clinical application of pancreatic CT perfusion imaging is promising.
