家兔肝脏低剂量CT灌注成像的可行性研究
The feasibility study of hepatic low-dose CT perfusion imaging in rabbit
摘要
Abstract
Objective:To explore the effect of hepatic lose-dose CT perfusion imaging for perfusion parameters and image qual-ity. Methods:9 rabbits were undergone routine dose,median dose and low-dose CT perfusion scanning. The original images were pro-cessed by perfusion software. The value of blood volume ( BV) ,blood flow ( BF) and arterial liver perfusion ( ALP) were measured and image quality were evaluated, and statistical analysis was performed. Results:The differences of BF, BV, and ALP among the three groups were not statistically significant (P>0. 05). The scores of image quality in routine dose group,median dose group and low-dose group were 4. 11 ± 0. 65,4. 38 ± 0. 61 and 4. 56 ± 0. 58,respectively. The two reviewers keep good consistency. Kappa value of two re-viewers was 0. 507. Compared with the routine dose group,the value of CTDIvol and DLP of the low-dose group decreased 75%. Con-clusion:Low-dose hepatic CT perfusion imaging based on reducing tube current in rabbit was feasible.关键词
