| 摘 要： | 目前,胰腺的影像学诊断逐渐从常规CT扫描单一的形态学诊断向CT灌注形态和功能学并重诊断转变;CT灌注是在常规CT扫描基础上发展起来的一种功能影像成像技术,通过CT灌注观察胰腺微循环变化可以早期诊断胰腺疾病,在胰腺疾病研究领域中是热点;用常规条件行CT灌注扫描,明显地增加了患者的辐射剂量,如何行低辐射剂量CT灌注成为当前重点探讨方向。本文综述胰腺低剂量CT灌注扫描成像技术应用现状及研究趋势。

| Abstract: | At present, imaging diagnosis of the pancreas is gradually changed from the single morphological diagnosis to combining of morphological and functional diagnosis in the CT perfusion; CT perfusion is a kind of functional imaging technology developed on the basis of conventional CT scan, which could earlier detect and diagnose the pancreatic diseases by observing the pancreas microcirculation changes using CT perfusion. It is a hotspot in the research field of the pancreas disease. Radiation dose was significantly increased using CT perfusion scanning with conventional scanning conditions. How to do low dose CT perfusion becomes the key direction of current discussion. This review deals with the application status and research trends of the technology in the low-dose CT perfusion imaging of pancreas. |
