ABSTRACT
Objective To evaluate the clinical value of 3D-FS-SPGR and 3D-reconstructional technique in detecting the lesion of articular cartilage of knee.Methods Fifty eight knees with OA(42 cases)or trauma (9 cases) in 54 cases (12 cases were confirmed by operation) were imaged with eight different MR imaging sequences including T 1-weighted,proton density-weighted,T 2-weighted FSE,STIR,3D-FS-SPGR,2D-FS-SPGR,3D-SPGR and 3D-FS-GRE.The classification and three-dimensional reconstruction of cartilage in four locations of knee were performed on different MR sequences.The detecting rate of cartilage lesion were calculated.The results in partly cases were analysed compared to operation. Results The detecting rate was different on each sequence as follow:T 1WI,GRE,STIR,PDWI,T 2WI and SPGR were 8.91%,16.36%,19.32%,19.57%,21.36% and 24.09% respectively (? 2=23.523,?
