Objective To evaluate the effects of high-concentration contrast media(400 mgI/ml)with low flow rate on the cerebral CT perfusion imaging of healthy rabbits.Methods Twelve New Zealand white rabbits were randomly separated into three groups.They underwent cerebral CT perfusion imaging with protocol A(Iomeprol:400 mgI/ml,flow rate:1.0 ml/s),protocol B(Iomeprol:400 mgI/ml,flow rate:0.5 ml/s),protocol C(300 mgI/ml,flow rate:1.0 ml/s).The total iodine for each injection was 0.5 g/kg.CBFs,CBVs,MTTs,TTPs and CT values of middle cerebral artery of each protocol were acquired and compared statistically.Results The mean CBFs of three protocol were(69.8±11.4),(72.2±12.8),and(74.8±10.3)ml/(min·100 g)respectively(P=0.759).The mean CBVs of three protocol were(2.5±0.3)ml/100 g,(2.7±0.2)ml/100 g,(2.6±0.3)ml/100 g,respectively.The mean MTTs of three protocol were(2.27±0.19)s,(2.30±0.26)s,(2.55±0.30)s,respectively.The TTPs of three protocol were 4 s,5 s,5 s respectively.And mean CT value([193.5±5.1]HU)of middle cerebral artery at peak time was higher than that of protocol B([164.7±5.2]HU)and protocol C([163.0±7.1]HU),but the difference between protocol B and protocol C was not significant.Conclusion Cerebral CT perfusion imaging of healthy rabbits using high-concentration contrast media with low flow rate will not affect the perfusion parameters.Under same injection rate,high-concentration contrast media may improve the display of vessels.
