摘　　要：近十年随着多层螺旋CT(MSCT)空间分辨技术的不断进步,薄层多期扫描、曲面重建、三维血管重建、灌注成像等技术的应用,可获得清晰的胰腺自身、胰周血管和胰胆管等结构的解剖图像,还可检测出肿瘤血流动力学改变。MSCT成像技术的发展,显著提高了胰腺微小肿块的检出率,有助于对肿瘤术前精确分期和手术可切除性的判断,使得胰腺的早期定性诊断和治疗有了明显的改善。Multi-slice spiral CT （MSCT） evaluation of pancreatic masses allows data to be acquired during optimal pancreatic enhancement, which aids in tumor detection. This technology permits thinner slices to be acquired during multiphasic scanning, with improved spatial resolution. The use of curved planar reconstruction and 3-dimensional representations of the vascular structures helps in accurate staging of pancreatic tumors and aids in successful surgical resection. It is significant clinical value that MSCT perfusion imaging analyze the chang of the blood flow for pancreatic cancer. Since MSCT technologic advances facilitate early detection of small pancreatic lesions, they are likely to impact the diagnosis and treatment of pancreatic tumors.
