摘要: Background It is difficult to distinguish solitary of fibrous tumor/hemangiopericytoma (SFT/HPC) from atypical meningioma (AM) by conventional imaging.As far as we know,diffusion weighting imaging may identify them effectively. Objective The purpose this study was determine the role apparent diffusion coefficient (ADC) values and predict prognosis (WHOII) (AM). Methods Preoperative diffusion-weighted (DWI) 30 cases with histopathologic immunhistochemical testified SFT/HPC WHOII (n= 11) AM 19) were performed retrospectively. ADC lesion, peritumoral edema, normal white matter lesion NADC ratio (lesion values/ADC (NWN ADC)) compared. markers (Ki-67, CD34, Vim, EMA, GFAP, S-100, PR, CD56) correlation between Ki-67 index evaluated. Results mean (1.15 ± 0.04 × 10-3 mm2/s) significantly higher than that (0.80 (t= 23.824, p 0.05) . (7.18 2.60%) lower (13.58 4.50%) (t=-4.934, 0.05). pearson analysis indicated there a negative in group (r=-0.770, (r= 0.202, p> Conclusions ADC, edema can WHO II be helpful two tumors before operation. Further more, make definite diagnosis tumors.
