Objective To evaluate the comparative cost-effectiveness of thrombolysis treatment of ischemic stroke based on outcomes of CT perfusion (CTP). Methods We applied the methods of systematic review to evaluate the studies abroad about the cost effectiveness of CTP diagnosis outcomes used for selecting stroke patients for thrombolysis treatment. We also evaluated the domestic studies about the cost-effectiveness of CTP in China by establishing a decision tree model. Results A total of 2 economics studies were included. The results showed that, the cost-effectiveness ratios of CT, CTP and MRI for selecting stroke patients for thrombolysis treatment were 2 983.7 ￡/QALY, 2 951.4 ￡/QALY and 2 982.9 ￡/ QALY, respectively, in the UK; 100 483.5＄/QALY and 99 406.1＄/QALY just for CT and CTP, respectively, in the US; and the evaluation outcomes by establishing the decision tree model showed that, 113 492.4 ￥/QALY, 113 615￥/QALY and 120 831.9 ￥/QALY, respectively, in China. Conclusion All international and domestic studies' results show that CTP is more cost-effective than CT/MRI in selecting stroke patients for thrombolysis treatment.
