CT灌注作为一种反映组织血管的技术,可结合螺旋CT用于疾病诊断、判断预后以及进行治疗效果的评价。研究结果显示,CT灌注参数在正常胰腺组织及胰腺肿瘤、急性胰腺炎、胰岛细胞瘤中差异,具有显著性统计学意义,但这还处于初步研究阶段,正常和异常组的灌注参数均值和标准误都存在较大范围的交叉,而且不同研究报道的结果也有较大差异,仍需要探索新的更科学的CT灌注参数。这些参数必须充分考虑到不同患者的生理个性,如体质量、身高、年龄、心排血量等等。
CT perfusion, as a technique that reflects the blood vessels in the tissues, can be used in combination with spiral CT in the diagnosis of diseases, the prognosis of prognosis and the evaluation of the therapeutic effect. The results showed that CT perfusion parameters in normal pancreatic and pancreatic tumors, acute pancreatitis, islet cell tumors in the difference was statistically significant, but this is still in the preliminary study stage, normal and abnormal group perfusion parameters mean and standard There is a wide range of cross-errors, and the results of different studies also have great differences, still need to explore new and more scientific CT perfusion parameters. These parameters must take into account the different physiological characteristics of patients, such as body mass, height, age, cardiac output and so on.
