Abstract: Objective To compare the diagnostic accuracy of 3D-DESS sequences with 30°and 90°flip angles for the knee articular cartilage injury (≥Grade 2).Methods Images of 13 patients (2 men,1 1 women,age range 18-68 years)of the knee articular carti-lage injury were obtained with 3D-DESS flip angles of 30°and 90°at 1.5T MR.Two radiologists classified the presence or absence of cartilage damage of ≥Grade 2 as positive (P)or
