Abstract:
Objective To compare the differences of the result measuring infarct core and hypoperfusion with imSTROKE and RAPID software.Method This study collected medical imaging examination data from 611 patients with acute ischemic stroke,349 of them were examined by CTP and 262 of them were examined by PWI,DWI and ADC.The volumes of infarct core and hypoperfusion were respectively analyzed by RAPID and imSTROKE software.We used Bland-Altman analysis and intraclass correlation coefficient (ICC) as agreement assessment method between two software,and 25 ml,50 ml,70 ml set as the assessment point of accuracy for estimating infarct core volumes.45 ml,90 ml,125 ml set as the assessment point of accuracy for estimating infarct core volumes.Result The median volumes of hypoperfusion and infarct core are 68.20 ml and 29.18 ml with imSTROKE software,while the median volumes of hypoperfusion and infarct core are 68.55 ml and 29.53 ml with RAPID software.ICCs (95%CI) of the result measuring infarct core and hypoperfusion with imSTROKE and RAPID software are 0.9885 (0.9865~0.9902) and 0.9880 (0.9860~0.9898).Conclusion imSTROKE has high agreement with RAPID in the estimation of infarct core volumes and penumbra volumes.Both of them can be used to measure the volume of hypoperfusion and infarct core.
