[Abstract] Objective: To evaluate the inter-observer agreement of three different FVH (FLAIR vascular hyperintensity) scoring methods.Materials and Methods: MRI images of 179 patients who were diagnosed with ischemic cerebrovascular disease during the time between June 2016 and June 2017 in Affiliated Hospital of Yangzhou University were collected. Three radiologists were invited to evaluate both sides of the MCA feeding area of each patient independently with three different FVH scoring methods. The inter-observer agreement of the scoring was examined by Kappa test and Kendall test.Results: The coincidence rates of Lee method, Olindo method, Olindo method (after grouping), Improved ASPECT method, and improved ASPECT method (after grouping) are 68.7%, 26.0%, 51.1%, 41.1% and 60.1% respectively. The average inter-observer agreement Kappa values for these methods are 0.652, 0.304, 0.530, 0.427 and 0.612 (P<0.001), and the related value of conformance of the methods among the reviewers are 0.882, 0.924, 0.900, 0.920 and 0.909 (P<0.001) respectively, indicated by Kendall test.Conclusions: Lee method has the best inter-observer agreement (high conformance). Olindo method and improved ASPECT method have a lower inter-observer agreement (lower and moderate conformance), but after grouping, they both get improved (moderate and high conformance). Clinic application should choose an appropriate FVH scoring method based on the evaluation purpose and the degree of differentiation.
