• To investigate the application of adaptive statistical iterative reconstruction-V (ASIR-V) in contrast-enhanced abdominal CT scanning with low-dose for liver cirrhosis. From June 2017 to May 2018, a total of 112 liver cirrhosis patients who underwent contrast-enhanced abdominal CT scanning were collected prospectively as the study group. According to Child-Pugh grading of liver function, the study group was divided into A, B and C groups. Thirty examiners with normal liver function who underwent contrast-enhanced abdominal CT scanning no abdominal diseases were collected as the control group. The control group applied 0 pre-ASIR-V. The study group applied 30%, 40% and 50% pre-ASIR-V in plain scanning, arterial and portal vein phase, respectively. The control and study group both combined with 60% post-ASIR-V. The difference of qualitative parameters (contrast to noise ratio of the liver, pancreas, spleen, abdominal aorta and portal vein), image noise and radiation dose were compared by .
