Liver computed tomography(CT)perfusion is a noninvasive imaging technology which can quantitatively investigate liver function,and it is mainly used in the diagnosis of liver tumors and assessment of liver function in the state of chronic liver diseases.The use of liver CT perfusion was limited in the past because of the high radiation dose.Now new technologies are exploited and they make it possible to reduce the radiation burden while maintaining the imaging quality.This article discusses the research progress of low radiation dose CT perfusion in 3aspects,including X-ray source,reconstruction algorithm,and improvement of CT scanners and optimization of scanning parameters.Although there are not too many studies of low radiation dose CT perfusion on liver now and many problems need to be solved,the clinical application of it will be very prospective.
